Iladan

Iladan is a material obtained from the colded lava of the volcano Tundea that comes from the unnatural even of the tundea's awakening that happens every few weeks.   The material is great as a fuel although it doesn't seem to be consumed when used as fuel, only exhausted. Once the material is exhausted, it is like throwing a piece of stone to fire, it won't provide the fuel it needs to keep alive and will eventually extinguish the heat-source.   It seem slike the material regains its propiety of working as fuel after being exposed to sun or other heat-sources. THe rock itself has vein like marks of dark orange around itself, the lighter the orange is, the more it can fuel, the darker it is, the more exhausted it is. WHen the veins are fully black, it has no fueling power and ahs to be refilled.   This material is extremly rare, as it only appears on small quantities after the lava from teh Tundea's awakening events is cooled, and the event only started happening a couple of decades ago, and happens every few weeks.   To gather these rocks, it is needed to walk over cooled lava, which, while it is cooled lava, it is still very hot and special equipment is needed. After reaching the place, one needs to find pieces of the iladan, which not always appear on the surface and while obsidian is easy to break, as it is fragile, the iladan is also in a very fragile status before it is exhausted for a first time, and if it is broken, it loses all fuel propieties.   THe rock itself isn't too easy to locate either, its color being very similar as the one from the cooled lava. A way of making it easier to find is making it enter in contact with water. Taht will make the whole rock shine in a soft orange light. This light can be seen (if water manages to reach it first) through a few centimetres of obsidian.
