I have another question about Under the Burning Suns. In the future world of Iydra where there are two suns, has the entire land been scorched and is it all desert (or are there other countries that still have normal forest and grass)? (most of the land that is seen in the campaign UtBS is desert - is this because of the two suns making Iydra much hotter?
Assuming Irdya is similarly structured as our planet Earth, devastating climate changes would have been caused by each additional sun.
Average temperatures across the world would have arisen considerably following the launch of the second sun, whereas the launch of an third would have probably turned the landscape into an scorching hell should it had been succesfull(sounds like an nefarious plan of an infernal entity?). However it failed so only the damage inflicted by the second sun remained continously in effect, essentially turning temperate landscapes to hot arid lands and frozen reaches into temperate climate as the ices melt away.
So its possible that there remaint greener lands and steppes up high north, an subject Umc like IftU touches.
