Golthar's Sky

Golthar's Sky was no ordinary starship. When, over 4,000 years before the Battle of Yavin, it approached the Foerost Shipyard in the Galactic Republic asking for hull repairs, the technicians were shocked at the immense size of the vessel, and asked them to hold while they sent out an inspection crew.

It was all in vain however, for the ship was merely a Force illusion created by Ulic Qel-Droma's accomplice, Aleema. It was so huge that it concealed several Sith battleships, with which Ulic used to take the Republic by surprise.
