help with name

hi, i am working on a champion concept, and so far i've finished the kit. the lore and artwork still in progress, but the name is my problem right now. first his name was Lodricar, the last god. then it was Zahr kar, the forgotten. but now i dont find those names as appealing as before.. can you, my fellow summoners, help me with this? i'm looking for a name that shows that this champion is mysterious, unknown, ancient (not like physical, but that shows he is from a time way older than gnar/liss that as far as ik they are the oldest champs in LoL atm), and that represents my champ. he is kind of a soul reaper, apprentice to death... (wont say more so i dont spoil Lore.)... any ideas? looking for something original and that as i said, represents those qualities.
