I understand your concerns, getting Alastor back is the main plot-point and if we can't get that to work, the RP will just be slice-of-life with Alastor slowly adjusting to a life as human. There will be no real end to it and won't bring new interesting problems to deal with.

If you want to cancel, that's okay with me. 

If you want to know if I have any ideas to get Alastor back, the only thing I can think of is a cave or a hidden temple with mysterious runes. Andy's brother is an archaeologist and could have found this cave or temple with the team during an excavation, and tells Andy about it, who then tells Alastor about it.
