Uhm that's a good question, not sure
I need to check the script better (or look in the wiki which is really being helpful recently!)
There are some names from there but not many. That said, I also included some references that Aleema had in various parts of these forums, such as Karen's mother, Uren, or Myrth's distant ancestor Mother Nature (whether you give it as a title or not).
Something you may wish to do is take a peek at Magic Stones (or I can compile a list of those names here). A lot of them would make good 'historic' figures.
These are some druids from Magic Stones. Obviously, you may wish to repurpose them if you make them part of the history of your current version of Aravorn:
Some personal favorites:
Anja: Female student of the master Druid Thanatos. Okay, Thanatos already sounds like a good name for a necromancer (yes, God of the dead and all that). And if his student surpassed him...
Eratoj: Reclusive mad man and sage. Has a fondness for succubi (looking at Jul, don't we all? Even better...what if Jul knew of him?)
Iodice: Formerly a nymph...(a story from her what stopped her being a nymph?).
Mgorem: Nicknamed the 'Rock'. Views men as criminals for their acts against nature. (Although you do have a demon named Mgorem in Spirited Hearts. Maybe named in honor of this one?)
Rebrow: The druid of the wind who rides his unicorn (heh...looks like pegasus and unicorn was mixed up in game
Unther: Founder of the Black Tower (he could represent the vicious side of druidism)
Other people mentioned:
Janob: An old male hermit who competes just to prove he can.
Terio: Male humble farmer who is a now a master of earth magic.
Peilane: Female, shadowy druid known for her grand thefts.
Ominz: Mercenary bounty hunter known for targeting victims for their magical artifacts.
Mihra: Female once renowned for her beauty, but became more malevolent as she grew older. Her beauty faded, but power grew.
Janimef: Just, wise man but has some temper issues.
Yamur: Raiser of hell hounds. It would be interesting if he bred the hellhounds (Trouble's ancestors) and they got loose...
Nindeloi: Reclusive water witch who refuses apprentices.
Nisia: Slender boy known for fire magics.
Hancka: King's son who gave up the army to study magic.
