It was once believed that the world was surrounded by a wall of ice, and in this cosmology, Sneasler were the first astronauts – a species of skilled climbers who glimpsed the worlds beyond the poles. In truth, nothing stretches quite so high, and the worlds of Beheeyem and the Ultra Beasts require one to reach speeds which Sneasler can not match. Yet legendary pokemon are often known to reside on mountaintops, which Sneasler climb eagerly; I myself have been interrupted by one of these pokemon sneaking into the Hall of Origin, which it surely considered a feat meriting great renown.
The mountains Sneasler call home may not quite merit the title of another world, but it might as well be from the perspective of the ground below. Wars do not easily reach this high, and in some peaks of the Alabaster Mountains (if not on the famous Mount Coronet, itself) the region is still called Hisui. Johto's Sneasel and Weavile have struggled to colonize these high peaks, and those nearest the mountaintops have a notable introgression of Hisuian DNA. The two populations readily interbreed, but there are peaks too high, terrain too foreboding, for even the ice-type Weavile to climb.
Few other pokemon can reach the terrain where Sneasler thrive, but they do not mind the solitude. Like Snom in a very different part of the world, these pokemon can easily meet their water needs by devouring snow, while the odd Rufflet, Bergmite, or Chingling which strays too high offers a rare but delicious meal. Human mountain climbers often think of Sneasler as a dangerous, silent assassin, but in truth they are as likely to rescue as to kill, and most of their victims, slowly expiring to the elements, might have, looking back, eventually regarded their actions as merciful.
