The Liga crystal, a spherical, non-transparent object that shone with a purple light, was discovered in the depths of Coruscant's underworld in the Imperial Era. It appeared to possess capabilities similar to the Force, for example, guiding a Force-sensitive individual, or others, towards a specific destination. An example of this was when it aided Leia Organa and Holdo in their search for a hidden location within Coruscant's restricted zones, by causing Leia's hands to emit a brighter glow as they approached their goal. At that time, the Crystal belonged to the Zeltron named Forzaa.
