This is based off of a story I'm writing, and technically he's a Light elf, though he doesn't look like one.
He is the dáskalos (teacher in Greek) of another elf named Conrad.
When the dáskalos is first introduced it's near the middle and he is giving orders for Conrad to go back to Greece or break ties with the main character, who is a Light Creature that’s half-nymph, half-fairy named Fae. Conrad has fallen in love and made it his duty to protect her, so he stays, but it means going against orders from his dáskalos.
That's a little bit of what the dáskalos is about. I know a bit freaky without the rest of his head! But trust me, he's cool...mostly.
