Antar

Antar is a mage who excels at preservation and sterilization using ice magic. He's great at brewing potions and assisting plague and nature mages in biological spells by providing them with fresh and sterile reagents from across Sornieth and freezing flesh and plant matter to keep them preserved and stable while they're being worked on or researched. His true specialty is "hibernation", and by hibernation he means freezing dragons in suspended animation until they are of use to the clan. Cruel as it seems, it works and doesn't seem especially painful or uncomfortable to affected dragons and it saves on food while they "hibernate", so the clan feels comfortable letting him do it (after consulting the rest of the clan). He really, really hates getting his claws dirty, children and overly sour food, though he loves sweet and bitter apples and fruity ciders. He shines his best when working with other magicians but is rather antisocial, preferring to work on his own and not share secrets. In fact, he enchanted his spellbook to only let itself be opened and read by him and him alone. He doesn't know his parents, but he must have some coatl in his ancestry, as his wings are feathered instead of leathery and he hums while he works.

Notes:
His green wings are not his real wings, but rather, his feathered wings. Pretend like his green wings don't exist. He has a little bit of down instead of scales near his eyes and on his belly.
His candles do not use flame but rather ice shards enchanted by a light dragon; using flame candles might drip wax or thaw specimens, but he still needs light to work.
He drinks his cider cold while he works but prefers it hot.
He has small spikes on his tail like those of a ridgeback, but smaller and blunter.
His skin gets pale when he works his magic or gets sleepy, like how a coatl's plumage fades when it sickens.
