Misandra is an infernal being who specialises in selling and buying Charms.
She will often trade her most potent charms which are in the form of a tattoo for a period of service to do her bidding.
"Misandra's Kiss" will grant its recipient a boost to Constitution, raising it to 20 or giving a +2 whichever is the higher. The recipient must then serve Misandra for 1 year and 1 day and do her bidding, this can be refused but upon the 3 refusal the deal is broken and the Kiss disappears and so does its benefit.
She takes a strong interest in the Beleth region of Weyland and her interest has been particularly peaked by the current state of war going on.
She has currently decided to throw her lot in with the "Harper" faction as she despises the Brotherhood more.
