Tyrwas
From MediaWiki

Tyrwas is the name of a fictional god of the sky worshipped by pagan Satanic worshippers destined to burn in hell wizards in the mythical land of Camelot. Like Beorht.
Leaving aside control of thunder, lightning, rain, and clouds, Tyrwas also appears to be responsible for recharging metal knights who, in 543 A.D., lack a suitable power socket into which they can plug themselves.
