As an ice troll, Ísólfur is a humanoid giant of wintry coloration. Overall his kind looks quite human, with long tapering noses, large ears, and gigantic lower canines that jut from the mouth like boar tusks. Troll males are generally ugly, but Ísólfur is less so than most. His lose is long with a bit of a hook to it, and his face is gaunt and leathery, not so much aged as fierce and vicious, like a hungry wolf. His skin is a pure, snowy white, and scarred with decades' worth of battles both with other trolls and with meals that fought back. His hair is a grey so pale that it's almost white itself, cresting into a warrior's mohawk in front and trailing into a thin ponytail at the back. His eyes are a dark sapphire blue, brightly standing out from his overall paleness. His clothing is made of stitched animal furs, forming a pair of shorts whose only purpose is for modesty, since ice trolls don't feel the cold. His feet are always bare.

Ísólfur is a sour-tempered malcontent. Jealous and resentful of his older sister, he'd up and leave her if he didn't know she'd hunt him down and smack him back in place... and if he didn't know living on his own would be far harder than sticking with his siblings. He doesn't like Skussi-Peyi at all and is especially resentful of the vow Galtroppa made to their dying parents: that they would always look after the runt.

He gets along fine with Skrumari, though, and the pair of them together act much the way brothers are expected to, joking and roughing around, making bawdy jokes and goofing off with no care for how Galtroppa rolls her eyes at them.
