Thrym

From Ardrana

Thrym is both the lord and deity of the frost giants, especially those of the Crystal Mountains. He can plunge any part of northern Ardann i'Parastha into a state of extreme cold. Thrym hates the gods of that region and will lend his aid to any plan that troubles them. Thrym often grants his followers the ability to use arcane magic.

Note: Thrym originally appeared in this form in Legends & Lore for the AD&D game from TSR. His use here is for the purposes of providing context for the campaign only.
