Friendly Fire is an elemental spell that allows an aitielkh to spontaneously cast a warm campfire for staving off the cold or even heating food for guests. There could be a variety of uses for such a spell. The flames require fuel (dry plant matter) in order to continue to burn.
The aitielkh can now summon more powerful flames to surround and protect areas. They can also create flames of different colors. Flames draw on the aiti's energy unless fuel is provided.
The aitielkh can use fire offensively if needed, in the form of fireballs. They can also create harmless will-o-wisps to secretly guide travelers, or benignly warm the earth to melt snow, ice, or permafrost.
