Hurakan

The Hurakan was a strange, unidentified entity which once resided within the Dark Sea on Sol'Mund. It was recognized by the ancient sol'mundians as a god of evil, as it always came ashore from the ocean, which the sol'mundians believed to be evil.

It acted as a sort of kraken, destroying any and all ships and sailors that came near the center of the ocean. It was powerful in The Force, as demonstrated when it fought back Rakatan invaders, and defied the power of the Jedi, Sith, Republic, Empire, New Republic, First Order, and Kullat's Sith Empire almost effortlessly.

The very first docile contact it would make with a mundane being was with Ignan Volcovo, after sensing something important in his destiny, in 50 ABY.

It would sacrifice itself during that same year to defend an ancient relic at the bottom of the ocean that was of vital importance.
