With some Blood Knights exiled for their research in M'uru, it was realised that so too can other Dark Naaru powers be bent to their will.
With the teachings of old former High Elven paladins of the Silver Hand, some Void Elves have begun to attempt to cleanse their void.
Blood Elves can be Paladins - why can't Void Elves?
The idea here is one that builds off the old Blood Knight Lore. Back in the day, Blood Elves drained magic from the Naaru M'uru to acquire their power which later lead to the collapse and creation of a Dark Naaru. The concept here was to build upon that old idea of using energies from the Naaru to acquire Light-based powers, but flip it upon itself to drain those energies for Void themed powers.
This, of course, could lead to a rift within the Ren'dorei and lead some to lean more towards the light-side of the Naaru while others fully embrace its dark, twisted form.
The concept on the left (above) would essentially grant Void Elves a base-Paladin skin (for all those High Elves out there) while still leaning into the Void themed with the idea of a 'Void Paladin'.
The Riftblade spell kit would easily transfer to Void Elf Priests, Mages and even Warlocks to give them all a 'Void theme'
