Quantum Collosus was a passenger starship that traveled between Coruscant and Eriadu, reverting out of hyperspace along several worlds on the Hydian Way. The ship was designed to be as sleek as the deep sea creature it was modeled after, and was considered one of the finest vessels of its type. It was in a cabin aboard the Quantum Collosus that Darth Sidious was ordained into the Sith Order by Darth Plagueis in 65 BBY.
