Zirrelian

Turnbuckle was a tentacled alien helmsman who served in the RLS Legacy during her expedition to find the legendary Treasure Planet of Captain Flint. Like nearly all of the crew, he was secretly a pirate and took part on the mutiny organized by Long John Silver.

Although they did manage to find the lost treasure; which was locked in the central chamber of the artificial planet; their entrance activated a trap mechanism which caused the chamber to shamble and deep trenches to open on the ground. Turnbuckle died along with another pirate when they fell into one of these trenches while trying to escape with some of the treasure; shortly before the planet's explosion.
