Adi Gallia is a Tholothian Jedi Master and High Council member, introduced in The Phantom Menace (1999) and played by Gin Clarke. In both continuities she is the Council seat closest to the Republic's intelligence apparatus, which is one of the few concrete jobs any of the background Masters is given.
Her death is a genuine continuity split. In the Legends comics she is killed during the Clone Wars by the Separatist commander Grievous; in the 2008 animated series she is killed by Savage Opress on Florrum. Same character, two irreconcilable endings, which is a compact illustration of what the 2014 Legends decision actually did to the Expanded Universe.
