The Dungeon Master's Guide provides optional rules for Feywild magic. One of these is Time Warp, where 1 day in the Feywild ranges from 1 minute to 1 year "everywhere else in the multiverse" (p. 50). It also states, "A wish spell can be used to remove the effect on up to ten creatures." (Ibid.)
If using the optional rules, when the Time Warp effect is removed do the creatures' ages change or do they move through time or something else entirely?
For example, in Faerûn, the party enters the Feywild and adventures for 1440 days (almost 4 years) and then returns.
- If 1 day in the Feywild = 1 minute everywhere else: The party returns 1 day after they left. Does wish reverse age them 1439 days or does it jump them forward in time 1439 days? If the former, are there experience point implications?
- If 1 day in the Feywild = 1 year everywhere else: The party returns almost 1444 years after they left. Does wish age the creatures 1440 years (effectively killing them) or do they jump back in time about 1436 years?
