Both Abduxuel and Ulviirryn recognize the flames by both from their color, faint acrid smell in air and way how the flames consumed the building.....it was a simple modified stoneburn acid. Normally such acid needs pressure to apply it on stones and it affects small accurate areas. But someone has been playing brilliant alchemist as this substance seems to be burning as fire instead pressured liquid! The fires eatting the building with intensity of the flames and behave pretty much like alchemical fire, meaning water does not work. Also where dirt would work it only feeds on flames which eat solid rock! But so far it seems the flames eat only stone, not organic matter but if exposed to long it starts eat it also.<br/><br/>So no water nor dirt will help put down the flames. Also what both can tell this is first time they see it but it had been theorisized before to create a burning stoneburner acid by changing it's components to more steamy alike and flamable when upon touching air to give it starting spark and then attach to whatever substance to spread. If not stopped these flames does not consume just warehouse.....but all warehouses in district.
