From Marge Hollander's Digest of Demons and Devils:
"Approximately three to four feet in length, the Erasti el Isnan, or Lover's Tongue, are considered one of the lesser Chimera. In Die Tür Des Bösen, this creature is referred to also as one of the Hungry, a class of cruel rapacious demons that manipulate bodily appetites. Reputed as petty demons of sexual obsession and jealousy, Erasti are often considered more pests than an actual demonic threat. Erasmus Möller's account of his encounter with the Arch Duke Grahtennas, gives an indication of the Erasti el Isnan as pets of the greater demons due to the delicate erotic pain of their stings.
