Magic, creeping abomination.
An oily pool.
Magic insinuates itself into everything we do.
Slides into cracks, coats hidden surfaces.
Collects in the low places.
It squirms, Slithers, amoeboid, pseudopodia.
Magic ruined the world.
Stain is everywhere.
Magic left us behind.
Now we hunt Magic.
Stench on our skins.
(How I would have treated Magic in Shards of Thimbral had that ever happened.)
