Yalasra
The world of Yalasra is a dangerous one. Primarily tropical and sub-tropical, it has only one desert (the kingdom of Solimensis), with some supernaturally-reinforced polar caps. Primarily land, it has just one large ocean and a somewhat smaller sea, though it does have plenty of lakes and rivers - including a canal that lines the entire equator, separating the northern content from the southern content.
Spinning in the opposite direction of Earth, Yalasra's sun rises in the west and sets in the east, and as it is much closer to its sun (making it a fairly warm-to-hot place to live), it also has a shorter year (311 days long). It is larger than Earth, about half again as large overall, with a slightly slower rotation, but its gravity, while heavy enough to be uncomfortable to those of Earth, is not harmful.
Filled to the brim with the incredible power that underlies reality, many are born with the ability to utilize this - a force which Yalasrans commonly refer to as alkos (translates literally as 'cosmic energy'). With this power, mages can alter the baseline reality, either temporarily or permanently as the spell's design dictates.
