I have a player whose personal schedule has become so chaotic that he can't make commitments at all for the foreseeable future. He has asked me to put his character in deep freeze until he can return. My problem is that his character has had some adventures that have affected the campaign world by giving rise to a brand new rumor-like legend (which gets the facts totally wrong but still relates to the effects of the character's actions). At some point it might be necessary for me to flesh out the legend and use it as an adventuring hook, which will mean having to thaw out the character and have her have done things the player didn't have her do. When the player comes back, he might be resuming with a higher-level character who has had summarized adventures he didn't play her through. I feel bad about that. Is there an alternative someone can suggest?
