Trelons are valued for their talons, which are long enough to be used as swordblades. When properly enchanted, they can become fearsome mage-slaying weapons. There have been tales that such weapons prefer to attack mages in combat, sometimes twisting in their owner’s grip to stab at magic-users, no matter what the intended target. There are rumors that trelons eventually come to reclaim the piece of their kin taken from them.
Trelon blood is said to give arrows of slaying (notably those that slay mages, illusionists, and shadows) extra abilities, but these abilities are unknown. Any attempt to use trelon blood to boost spellcasting or in a magical ritual has caused the spell to fail and has, in some circumstances, summoned a swarm of trelons to the scene.
