Osvald Ralgol

Osvald Ralgol was a captain in the Imperial Navy. He commanded the Victory I-class Star Destroyer Contagion as of 11 BBY. However, Ralgol came to despise Emperor Palpatine for his poor treatment of Imperial military personnel. He decided to try to overthrow the Emperor and replace his government. Ralgol recruited Lieutenant Vexler Narath and many other crewmen to his cause.

However, their initial plan was foiled by Lieutenant Martio Pavan, who reported their activities to Imperial Intelligence, which warned the Emperor. So instead they chose to ram the Contagion into the Imperial Palace in a kamikaze attack to kill Palpatine. However, only Ralgol, Narath, and a few other officers were aware of the new plan. Everyone else was told that they were simply landing to begin their coup against the Emperor. Ralgol and the select few who knew would make their way to the escape pods when everything was set. However, Pavan and an Imperial Navy trooper named Meshik Gallagane made it to the bridge, where they told everyone of Ralgol's suicidal plan. A firefight broke out between the hardline conspirators and the crewmen who were kept in the dark. During the shootout, Ralgol wa killed.

The coup was ultimately thwarted and the Contagion stopped before reaching the Palace.
