I have a question about the Philosopher's Stone reward. My founder only needs to get one more reward to fulfill that requirement, and I was thinking the Stone would suit nicely since she's an alchemist. Now, the Stone's 'bind ghost' utility would come in handy in the future, helping to bring in a ghost spouse, but the question is if this would be allowed or if only the future heir marrying the ghost is allowed to bind it? If so, I'll have the founder pick some other kind of reward I guess.
