A very flammable liquid.

Journal

Distilled from swamp tar and charcoal.
Once known as “thick water”, naptha is liquid fire in waiting. It takes little to bring this substance to ignition, even too bright a sunny day can bring the raging flame from within.
As such, this material is widely sought by anyone with a strong desire to set things aflame. Pyromaniacs, alchemists and dragon cultists alike yearn for this liquid.
