Fantastic one shot adventure. I ran it twice, with first time players, and it worked great. Since it's open-ended, I added a plot twist: Marcos is actually an evil sorcerer who wants the spheres for himself and is using the PCs for his purposes. Each sphere they take, in addition to increasing the evil in the forest, time passes faster, pushing them several years forward with. When they leave the temple they find a scene of devastation.
I translated the map, since one of the group were kids, and printed the letter from Marcos as a diegetic handout, to add flavor to the adventure kickoff.
Thanks for making this little fun adventure!
