It has been said that within the mountains (or was it the darklands?) there dwells a fluffy creature of immense cuteness. This creature is so adorable that all who encounter it are filled with joy so great their mortal forms cannot contain it. And they explode. Several magic institutions are desperate to study the creature or better yet capture one to prove the theory of an elemental plane of "D'Awwww".
What happens when, while in the middle of an important fight/Event, the mage that enchanted all your gear suddenly dies? Unless the enchantments outlive their source, you might not either.
