[Major Endgame Spoilers] A fantastic detail from the Jedi Enclave
If you have the Force Sight power from TSLRCM (I think that's the one that adds it) and look at the Jedi who have fallen, you'll see >!Vrook!< is almost neutral in the force, whereas >!Kavar!< and >!Zez-Kai Ell!< are strong in the light side. I'm sot surprised at all.
