Everburning oil

Everburning oil, also called Greek fire by knowledgable wizards, was a mixture of oil and other substances designed for use in combat. It was easy to ignite but difficult to extinguish, and had a tendency to stick to anything it hit.

Use
Everburning oil was sometimes employed in the defense of cities or as armament of ships in so-called Greek fire projectors or flame cannons.

Distribution
In Zakhara it went by the name oil of stars or oil of liquid stars. The city of Qudra produced this dangerous substance, while the city of Ravens Bluff banned it in 1370 DR due to the risk it posed.
