We're Siths. Our emotions are heightened. I'm stubborn, Goddard is moral, and Marcus... Marcus has no tolerance for those who disappoint him. Over forty years as a family we've all made that mistake at least once. I've made it several times in fact.
Adriana Lai on her Sith "family" and son.

Marcus Lai, also known as Darth Letalis by the dark side Force-sensitive community, was the prince of the Galactic Empire and Darth Sidious' Shadow Hand. Marcus' full name was in fact Marcus Derek Lai. Foretold to be The Fallen in the Prophecy of the Dark King, Marcus Lai was destined to be the most powerful Sith in the history of the Dark side, making his Sith and the Dark side the most dominant force-sensitive group in the Galaxy.


Pre-Rebirth of Empire series

Birth and Childhood

Just over Two Years prior to the Naboo Crisis, Marcus was born to Senator Palpatine (a.k.a Darth Sidious) and the Nightsister Princess Adriana Lai during Palpatine's Sith pilgrimage to the Nightsisters looking for a certain Sith Holocron, during his search Palpatine fell in love with his Nightsister escort whom happened to be Princess Adriana Lai undercover who was observing the Sith Lord for her own mother: Nightsister Queen Zalem.

After his birth Adriana left Dathomir and decided to travel about the Universe after staying with Palpatine for about a year, by 30 BBY however she had learned about her mother's death and set out to return to Dathomir to keep her people in line while brining the knowledge she had garnered back with her. Marcus was left with Palpatine whom had instructions to train him in the Nightsister and Sith ways, to teach him of the dark side and to make him powerful through those ends, most of his childhood would then attest to being trained as Darth Sidious' Shadow Hand.

The Clone Wars

Around the Clone Wars, Marcus was quickly becoming a Man as his coming into the late teens, by the time of the First Battle of Geonosis he had been announced as Assistant Supreme Chancellor of the Republic and dubbed as "Prince of the Republic" by those whom personally knew him. It would be ironically that by late 20 BBY, that his mother would return to his life, bringing the Holocron of the Sith Emperor with her.

Rise of the Empire

Marcus was the first one to arrive with his Fleet to the Defence of Coruscant, Marcus would then fight alongside the defenders to force back the Confederacy of Independent Systems from the Capital World of the Republic, from there he was stationed in the Mid Rim hunting down Jedi and Separatists whom wouldn't surrender days after the announcement of Order 66. It would be during the next Six Years that Marcus would hunt after a very important Jedi in the grand scheme, the Jedi Knight's name was Stefan Thomas and due to the efforts of Darth Vader Stefan's Jedi Master Tial Roxarn, was felled in their attempts to flee Corellia after a botched act of Rebellion by Jedi Sympathists in the area.

Eventually Marcus would track Stefan to Korriban where his ship would be downed and where the two would fight in a duel at the Valley of the Dark Lords where Stefan would come to fall into the Dark side, their Soulmate Bond would cause either party to be unable to kill the other and therefore the purpose of the duel was convergence, Marcus succeeded in making an apprentice out of Stefan and decided to leave everything under his command with Adriana Lai while he and Stefan went on a pilgrimage to other Force sensitive cultures to learn their perspectives and abilities.

The time of Rebellion

When Marcus and Stefan returned in 2 BBY from their 11 years of Pilgrimage they were surprised by what they saw, the Empire's tyranny had given rise to a Rebellion and a number of Imperial Admirals were becoming discontent with the reign of Emperor Palpatine, many of the Imperial citizens however wanted out of the Emperor's reign and soon came to look to Marcus for aid. Marcus did exactly that, as the years went by loyal Imperials began to discreetly pull out of worlds that were Rebel targets indicated by Marcus' Dark Jedi spies within the Rebellion and other informants, Marcus pardoned Admiral Demetrius Zaarin and "banished" him into the Unknown Regions when really he was having the Admiral seek out hospitable worlds to move loyal Imperial Refugee populations onto.

Marcus gained the allegiance of then Vice Admiral Thrawn and by the time the alien was risen to the ranks of Grand Admiral, Marcus had already prepared his father's end game with two potential plots in mind: the Death Star II shift plot and Vader's Assassination plot, the first plot didn't go so well but it did serve its purpose by shaking up Palpatine. The time gap between the two plots allowed Marcus to politically and militarily take control of the Empire while the Emperor retired to his meditations, by the time the Emperor had learned of what happened it was time for the second plot as Marcus approached Darth Vader and the two agreed to duel Palpatine within his Palace.

Together the two Sith defeated and killed the Emperor however Anakin Skywalker decided to redeem himself at that moment by attempting to kill Marcus Lai whom has now inherited the title of Sith Grand Master under the Sith name Darth Letalis, before Anakin could bring balance to the Force however his apprentice Stefan Thomas with the title Darth Clavis stabbed Vader through the back, killing him.

Restoring Order to the Empire

With Emperor Palpatine's "murder" by Darth Vader, Marcus announced himself as the "Acting Galactic Emperor" thereby skipping his time consuming coronation and taking advantage of emergency powers during the current crisis, Marcus initiated a scorched earth policy where every ship or base attempted to be captured by the Rebellion would be destroyed or put into self-destruct. All loyal populace would be uprooted from rebellious worlds and moved to the Unknown Regions, where they would inhabit unoccupied worlds across those Regions, by protecting their families those related already recruited into the Imperial Military would be emboldened and continue to sacrifice themselves for the cause.

Abandoning non-essential worlds with those loyal also being moved allowed the Empire not exactly to lose territory so much as give it up, the Unknown Regions were as resourceful if not more so than the worlds being abandoned allowing the Empire to become a self-sufficient nation, Marcus centred the Empire's fortune along the Imperator Supply-line through the Unknown Regions based at the Mustafar system and the Bastion system but going through the Empire's New Capital system: the Diluculo system. The Supply-line stretched along the Tingel Arm to Sith Space (from there supplying Kessel, The Maw and Honoghr) and across to Kamino out in the Rim territories, the supply-line's final arms reached coreward. The farthest reaches of the supply-line from Bastion reached coreward to Cardia, Anaxes and Kuat, through a hidden Hyperspace Route they even reached the Deep Core. This would come to a head briefly in late 6 ABY when the Rebellion would take Coruscant, taking on the name of the "New Republic, planing to spread democracy throughout the Galaxy.

Within the next four years there would be continuous struggles between the New Republic and the Galactic Empire as it withdrew from irrelevant territories, Marcus would go to The Maw and from there he would begin Withdrawal plans for these secret labs, all completed works would be moved to the Lehon system (Rakata system or Star Forge system) where research was being carried on the remnants of the Star Force and where Lehon was becoming the HoloNet centre of researched and historical information in the Empire since Obroa-skai had become part of the New Republic. The Maw was rescheduled for new Research and all new research fields should be recorded in the Private records on Lehon, the technology researched was put to good use and using it the Acting Emperor managed to ruin many threats to the reorganising Empire, including threats such as Ysanne Isard and Trioculus whom attempted to work with traitorous Grand Admirals to remake the Empire as they wished - all were killed for these actions.

With all internal crisis and rebellions dealt with the Acting Galactic Emperor looked towards peace with external individuals bot more importantly, the Chiss and the New Republic, Marcus started this by assimilating the Empire of the Hand and their Chiss population under his command. Through the Chiss under his command coupled with making Grand Admiral Thrawn the Supreme Commander of the Imperial Forces, Marcus approached the Chiss Ascendency and by late 9 ABY he had made an alliance with the Ascendency, thereby protecting the Empire from the Rear and allowing him to move onto phase two of gaining peace in the Galaxy: the New Republic. Marcus launched the Thrawn campaign allowing Thrawn to begin a number of battles against the New Republic and turn the tide against the upstart nation, after the New Republic was forced to retreat after the Battle of Bilbringi they decided upon a Peace Treaty at Anaxes, there Marcus would also be Marcus Lai's Coronation as the Galactic Emperor which the peace would last for over seventeen years.

The Senate

Mas Amedda

Jedi Master Luke Skywalker

It was revealed that through his teachings with his Mother that those like them that followed the Sith Emperor's teachings looked at the Force different than either Sith or Jedi, the Sith dammed up the Force River and gained power from it while the Jedi let it flow through them, Letalis and those like him however considered themselves a generated whirlpool in the flow - a way to gain energy comparable to the Sith while like the Jedi not having to worry about corruption from the Force.
