The VOIDRUNNER'S CODEX is coming! Explore new worlds, fight oppressive empires, fend off fearsome aliens, and wield deadly psionics with this comprehensive boxed set expansion for 5E and A5E!
Arkine (just made it up but like how it sounds)
Sentinel (if you like that flavor)
Marvel (if you like that flavor)
Discordant (again, a flavor option)
It was already suggested they be called Baladhara for an Indian themed campaign.
Others I can think of are Dao Shi (essentially Taoist Priest) for a Chinese campaign. Myrmidon for a more Greek themed order or psychic warrior bodyguards.
