A fun back and forth using the "same" map but in different time periods. My players ended up figuring out the puzzles after they returned to the present, so they didn't have access to the tree branches, but they had fun telling future them that.

The layout was very good for helping me as the DM to prepare for this adventure. The maps have notated plot and interest points on them and the story is unique which in my opinion also helped keep the party on the story line rather than skipping 80% of an adventure with creative use of spells. You will definately want to record the party's questions they have for their future selves and ask it back to them when the time comes. I would strongly recommend buffing every monster or at least the last encounter if your party is well geared or has more than 4 players. As-is this adventure should take about 4 hours depending on how efficient your party is at dispatching foes.
