Grand Magus Eldavin is an alias that Teriarch uses among mortals when he wishes not to be recognized as his true persona.
The image of Eldavin is created as a projected Simulacrum that Teriarch can maintain over large distances without leaving his home.
Eldavin is an overly attractive old guy with a beard. His hair is a pale silvery white that has a luster and shine to it. His skin tone first appears to be white, but on second glance you notice that it is a moderate olive brown, but whitened from not being in the sun for a while. He has the body of model or athlete past his prime but with the same body, and wears magical robes that look shinier than silk. His eyes are both cerulean (azure-blue) and helioptrope (amethyst-violet), although the colors are of unnatural deepness, as they show a tiny bit of magic caught forever, and are ever-shifting their exact hues.
In the aftermath of his battle with Cognita, having forgotten that he is a Dragon. Eldavin's personality largely resembles Teriarch's. However, he lacks Teriarch's world-weariness and is eager to live. He is much less restrained in disseminating his magical knowledge to others and is intent on accumulatating political power in Wistram. Additionally, he is much more promiscuous, sleeping with several young women.
Teriarch used this appearance in his first three interactions with Ryoka while hiding his real body behind an illusion; although he used his real name in these exchanges. After she broke his spell that affected her memory, Ryoka confronted Teriarch with knowing the truth, and he stopped using the facade.
Teriarch was reminded of the name "Grand Magus Eldavin" which he had used for his dealings in the past, for example with Wistram. Wistram remembered and still sent out invitations for conferences or other gatherings. As Eldavin, he had not made a public appearance for decades, though.
When he next confronted Ryoka and Erin using the simulacrum facade in the ruins of Celum, Teriarch re-introduced himself to them as Eldavin, and urged Ryoka to not address him as Teriarch. He then followed the two Human women to The Wandering Inn, where he impressed everyone with his magical prowess, knowledge and age - admitting to have known Zelkyr and clearly demonstrating to be an ancient Grand Magus, humbling Grimalkin and all other Mages at the inn. True to his real personality, he was rather dismissive of most petitioners and acted aloof towards most of the people trying to gain his attention. Eldavin challenged Erin in chess and had difficulties beating her.
- (To Erin) “If you would crave anything, do not crave safety. Look towards the courage to walk through adversity. That is more valuable than any illusion. Treasure the moments you have, child.”
- (To Ryoka) “For friendship—move mountains. For friendship, challenge the will of the Faerie King. Do it, Ryoka Griffin. You are young. Dare it.”
- (To himself and Magnolia’s staff) “Hah. As if you’re the only one who can conduct trade deals, you little brat! That was so amusing. Ah, well…where’s my popcorn? The inn was faster than this!”
- (To Erin) “I don’t play chess for lack of suitable opponents. I myself am something of a… master.”
- (To Erin) “One more game takes all. But we’re betting on this one. I won’t lose again!”
- (To Fetohep) “From the halls of Wistram, I offer you the aegis of magic, thou immortal scion. So long as sand shifts, let not Khelt’s deeds slip away. For every grain of sand called Khelt, every breath of air and drop of water is magic and Wistram’s blood.”
- (To viewers) “I see a ‘Sir Relz of Pallass’ has the courage to dignify this twaddle with his name. Regrettable, that. How can we ‘prove’ the two are linked? Perhaps with something as simple as our minds, you imbecile. I do not need to prove every single thing beyond a shadow of a doubt. If you breathe, you can infer there is air. Arguing for complete proof is a child’s gambit.”
