On Interesting Treasure: The Idol of Ilkos
This ancient electrum amulet shows the feline incarnation of Ilkos, resting upon an Aegis representing the chaotic planes of death, disorder, and entropy.
The bearer of this amulet often finds that cats stop activities and watch the bearer. Any attempt to approach and they flee. If ignored, they just stare at the bearer as if awaiting something.
It is worth 200 gold to a collector, or 15 gold as a curiosity, but rapidly degrades in value as bearer after bearer attempts to sell or dispose of the piece.
