Possibly the Creator of the universe got bored with all the usual business of axial inclination, albedos and rotational velocities, and decided to have a bit of fun for once. It would be a pretty good bet that the gods of a world like this probably do not play chess and indeed this is the case. In fact no gods anywhere play chess. They haven't got the imagination. A lot of it ends up in the Ramtop Mountains, which stretch from the frozen lands near the Hub all the way, via a lengthy archipelago, to the warm seas which flow endlessly into space over the Rim.
Raw magic crackles invisibly from peak to peak and earths itself in the mountains.
It is the Ramtops that supply the world with most of its witches and wizards. In the Ramtops the leaves on the trees move even when there is no breeze. Rocks go for a stroll of an evening. At times, so does the sky. The storm was really giving it everything it had.
