The soul of a mage has been trapped in his own bust for centuries. The bust is a foot in height and made of a dark silvery metal. It is well crafted, perfect in every detail of the mage's features. The frozen expression is one of shock. It was sold off in auction after the mage's unexplained disappearance and has been passed around as a curio ever since. The cause of his entrapment? He practiced in secret; none knew of his hobby. Being self taught, he was unable to tell that the spell he thought was for protection was actually for entrapment...
Arkths or Ravagers: These are large landbound crablike creatures about the size of Grizzly Bears. They live partially in the astreal plane. Their food is magic. They can sense it at huge distances. Since spells and such are hard to eat (being in motion) and magical places are the equivalent of a sea of krill to them, they are looking for magic stashed in concrete places. Their primary food source is magic items, alchemical potions, and enchantments. They do a pretty good job of mangling/ eating the physical aspect of said items in the process of chowing down. These things will be the bane of dungeons everywhere, as they will slowly eat away much of the treasure (and the magical traps... so it can be advantagous to follow these things). Note: They will attack people with highly magical natures (i.e. high magic powers). They will probably kill the person in the process of sucking out the power.
