"How is he? Will my son ever recover from the bugs that turned his brain to mush?"
The doctor pointed to where the thirty-seven year old was playing with toys on the floor. "It's been five years now and he has the brain of a child, give it another five and we can start the basics of teaching him magic again. He knows who you are but...but he will never have the same personality again, and by the time he regains all his magic skills at their former levels he will be in his sixties."
And in the name of the great and powerful I command thee to return to your body, hearth and soul, so that you might walk again and continue in the gods plans.
See that. . . wait. . . what!?! NO! I knew it was too risky here. You have brought ruin to us all. Why you ask? Ready your weapon, a traveler has come.
-Father Hayden, performing a ritual on the deceased outside the protection of the church.
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.
