Penguin

Penguin is an animus IceWing mentioned by Arctic in Darkstalker. His gift to the tribe was the gift of diplomacy, a heated dome near the border of the Ice Kingdom. He did not enchant the dome to build itself, as the dome was carved by other IceWings. He simply enchanted the dome to provide extra heat for them so their guests wouldn't be uncomfortable in the cold.

He may also have enchanted the three bracelets meant to get non-IceWings over the wall and keep them warm in the freezing temperatures, though this is not proven.
