(Middle school level)
You can't miss Thrym. No, really, you can't miss him: he's huge. He really stands out in (or head and shoulders above) a crowd. Look for a guy surrounded by horses and dogs wearing gold leashes. They're his pets, and he's very attached to them. In his spare time, Thrym likes to sit on mounds, petting his canine friends. Just another day in Jötunheim.

Jewelry and accessories: Gold dog leashes. But they're not for him, they're for his dogs.

His old, unlucky sister
His dogs and horses
His mead hall
