We were summoned to assist a Dryad by the name of Maple. When finally we managed to get away from the world's most interesting sign, we learned the forest has been overrun with parasitic mushrooms.
Tealight's tried to assist this before, but unfortunately, their solution of carving eyes into the trees to watch the mushrooms so they do not regenerate (something they do when damaged, so long as they go unwatched) failed only partially; the dryads, she mentioned, looked better than before.
Maple sent us to Shiitake, another dryad whose forest had experienced the same issue. Shiitake had survived by choosing to embrace the mushrooms were so many of her fellows died. On our way there, we were set upon by mushrooms made sentient and beasts infected with spores; the infection grows.
Shiitake, seeming somewhat complacent to the mushrooms (a side effect of joining with them, I'm sure) examined the mushroom we gave her and remarked it was many species of mushroom slammed into one. She suspects that the Drow man who did this to her forest, now all flesh-like mushroom and spores, is still experimenting and that it's spread.
She's asked for a few weeks to study the specimen and learn what she can. I fear Maple does not have a few weeks.
Jacob, a druid in the college of Silvery, was kind enough to teleport us back home.
