This world has two main sections where snow falls frequently. One of those sections is Richter's Kingdom, whose location is the closest area of the ability once released by Matthew, The Frozen Infinity.
On the other hand, the area opposite the Frozen Infinity, the south, is also an area where snow falls very frequently, somehow, but only centered in one place, something called The Devoured Mountains.
They get the name because they are part of the Devourer territories and because, in times past, they were a part of the vampire territory that was completely conquered by the offensives of the Devourers and their allies.
For those in the know, which are very few, this little story is false; the vampires did not lose an area of their territory from millions of years ago; traitors actually surrendered the whole area to the devourers.
