Summon thunder giant
Summon thunder giant is a calling of Pyre, the affinity of fire, destruction and war. It brings Thunder giant into its caster's own kingdom.
Summoned things are shapes that a spell calls out of the Welter, the raw power beyond the Covenant. Great figures are among them. Sealborn of Pyre say this one is a thunderhead given a body, towering and loud. It holds its shape because Wefan, the Weaver's Seal lets power keep the form of a spell, and Weaver's Call, the art Wefan, the Weaver teaches, helps a caster hold it. The unit's card sets its keep.
These figures come singly or in small numbers. A deeper realm brings more, and fewer come against the grain. The calling takes several turns as well as mana.
Guild artisans say the first to shape this figure was a newcomer of the Age of the First Sealborn. Every foreign soul remembers being somewhere else, and this one remembered storms.
