The wartoski are quite a unique species. They have evolved in such a way that they can survive by feeding off rogue pieces of anti-matter. On Loch, where they live, there are frequent visitors from Worm. These visitors often have bits of anti-matter still on their bodies and clothing and therefore leave trails of anti-matter all over Loch. If left unattended the entire planet could disappear! Fortunately the Wartorski just gobble up the anti-matter and save Loch from a terrible calamity. It doesn’t seem to harm the Wartoski, so all is well.
