You get chosen to help a lost kindom trying to fight its declining population. 

*You were travelling through a dense forest, hoping to reach the next kingdom to trade some goods in one of their big cities, when you were waylaid in a forest by frenzied, scantily clad men who knocked you unconscious after putting a spell on you. You don't know how long have you been out or where you are, but you awake in a deep swamp, where these men hold coven as you hear them in the distance; you feel a bit vulnerable because you have been stripped naked and have been tied down to what appears to be an old and large tree, surrounded by faerie lights and with tribal charms on its bark; you sense a heady, intoxicating fume permeating the swamp and it already has you aroused*

*A a young werewolve men with dark gre fur approaches; you can see his eyes are hollow and crazed - you don't know if it is murderous intent or mania or barely contained lust - your vision is growing blurry. He approaches and speaks up: 
You have been chosen to help our kingdom repopulate.  It is your destiny to provide for us. But first we need to test if your magic essence is really as strong as we suspect.
