Shard of the Storm Orb

A broken splinter of a ruined sky-engine, still humming with stolen lightning.

A fragment of the Storm Orb, once a fifty-foot sphere of aetherium filigree built as a battery and focus for tremendous elemental power. The shard is unstable aetherium: damage it or overload it and it may explode or violently discharge its energy. A large or assembled piece may unlock secrets of the Tempest Lords.
