The Magma Railgun

POV Vesuvius:

Thick black clouds drifted across the sky, lightning flashing and rumbling in them. A brightly glowing yellow lance of magma levitated in the air as if there was no gravity.

Two golden glowing eyes were looking straight at the lance, hidden between the black clouds, as a monumentally large dragon flapped his wings, hovering high above the white mountain, peaks under him.

'This time, it should work.'

Two bright lines of lightning flared up around the magma lance forming rails forged of plasma and electricity, shining across the sky and throwing blue sparks.

The lightning rails sparked in increasing intensity around the magma lance, blue sparks raining down from them, and electrical arcs connected with the lance.

The magma lance just remained to hover, only slowly moving forwards.

'Dammit, the magma simply isn't conductive enough. There is not enough current passing through it.'
