Dungeons & Dragons Online gives us a Monster Profile of the Bezekira and Jarilith.
Lions have always been among the most admired of the wild creatures of the world, and I agree that they are impressive. I once had the great fortune of going on safari in Lammania. (I won a door prize at some pretentious pseudo-intellectual gathering in Sharn once upon a time.) I must say that the trip was excellent.
