This finally finished with regular airing.
Also not 100% on the gold chains. net discussions, make a good allegorical point.
The captain was chained. and silna cut his hand off to free him. (of duty chained to his dead men.)
While the other leader, weighed down in gold chains, literally to his face, died, and lost his men.
He also failed repeatedly... we get a montage as the captain with silna follow after the crew, and find them all dead, one by one. ordered to leave, but expected to save the captain, men over ruled him. Ordered to leave no man behind. Left sick behind. we see the crew turned to cannibalism just like the mutineers. With the officer last alive.
Actual literal reason for it. no idea.
