Age versus Earth

An ancient man, crackling with arcane energies. Passing birds are electrocuted, and fall to the earth with a dull thud, smelling of cooked chicken.

Locked in a standoff conflict with:

A creature made of stone, earth and clay, bits of turf still attached, a gopher trying desperately to dodge the electricity.

Impossible to damage or destroy either participant, but they could damage each other with a little help.

Who to help?

Made more difficult by the fact that once involved in the battle, one or both sides summon reinforcements: either nearby plants and stones rise up in defense of the earth creature, or dozens of shockingly beautiful flying ethereal creatures come down to defend the ancient man.

After resolution, a previously unseen cloaked figure hiding nearby vanishes into a tornado-like cloud of leaves and dirt.
