I loved the Weird hook (I love the Strange)

The idea seems simple enough

So here's a twist on the subject

1: The Candidate is chosen by genetic compatibility which could include several choices
2: The Hunter must chose from those compatible 1 in the beginning and be successful in their capture and evasion of pursuit by the chosen's family and any authority brought to bare.
3: They must win the chosen over to the idea without force or threat. It is in this manner they prove the spiritual compatibility.
4: The Union must conceive within 1 year a healthy offspring

Failure may result in the Warrior loosing all status, rank, family connection and sterilization; in other words they become an outcast an the end of their genetic line
