A few questions about REGEN. The Permanent Trauma sidebar on page 70 calls it "an ancient drug." Who developed and manufactured it? Is it an Old Age product or a Enclave drug still in production?
Can it be used on any creature with permanent trauma from any source?
What would happen if the the players decided to give a dose to the Elder? My group is wily and there's almost no chance they wouldn't immediately think to do this and then grill the old man for answers. Saying that he died before they got back with the drug seems like a cop-out.
