A short adventuring interlude focusing more on encountering something unusual, rather than fighting anything.
The PCs come across a tree and a pool inhabited by elves. The nearby brook fizzes with "energy gas" that grants a temporary HP boost. The players can explore, but there are no real "answers" just a weird thing they found on the way from somewhere to somewhere else.
Rated for between 1 and 4 characters, this could easily be run for solo play, but it is short and a little weird. There are roleplaying opportunities with the elves, but there's scant data here, the elves are flighty and capricious.
This adventure doesn't have any pending change requests.
