The charm has no end duration, but can be negated by a remove curse spell or another power that removes the charmed condition. You relinquish the charm the next time you use this feature.",

It might see you as a tool to further these strange aims, bidding you on seemingly unconnected but always unsettling errands. Or, you might tap into its unspeakable power without so much as gaining the notice of its vast awareness, having learned the proper rituals in some maddening grimoire. If you have a name for your patron, it could be an ancient primordial, the King in Yellow, one of the gods of Pegana, or a being from the expanded Cthulhu mythos. Regardless, you can draw on strange and terrible magic from the Great Elder Thing.",
