“ Magic is the lifeforce of all living creatures, and it is from it that all life is made - in areas with lots of undead, magic might actually be missing or weak, which puts a whole new spin on how dangerous the undead are. Even simple zombies can be troublesome if you're relying on mages and you hit a pocket of undead making a low-magic zone...”
“ The ancient Empire of the Golden Crystal fell so long ago that little is known of them besides their legendary magical power. Supposedly, in the Golden Age of the Crystal Empire, cities were filled with enchantment, spells far beyong the ability of modern magi.
A tomb robber has returned to civilization with something never seen before: Ceramic vials of reddish dust that supposedly enhance a magician's power tremendously when the dust is sprinkled upon the floor of his workroom. The rogue selling the vials claims that they were recovered from a ruin of the Crystal Empire, but can he be believed?”
“ 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.”
