Wouldn't get involved, though it would be impossible to have avoided him/her this whole time. Since we don't know canonly what the WoL looks like, they could be anyone our characters have passed by by now.
As for interacting with them, my character has not. In the event that he has, he would be extremely vague about the identity to avoid the whole "I've met the WoL and know what they look like!" attention.
