Thunderbird is a mythical bird of lightning and storm. The name covers two distinct presences in the shared cosmos.

- A standard-invocation that acts as a family chronicle in Thunderbird (Family Chronicle), in the descent into hell: a colossal invocation that dies before Cerberus.
- The Thunderbirds of the Crown of the North gesta (campaign-cycle): potential allies protected by the great spirit Pomola, guardian of the mountains and birds.
The entity connects Native American magic with elemental thunder power. In planar terms it dwells between the Elemental Plane of Air and the domains of the nature spirit.
Sequoia, smith of the Crown of the North, wears gloves embroidered with Thunderbirds. Medawaywin, the life force of the land, binds its health to the fate of the sky spirits.
