From the introduction:
This quest takes the player characters through a harrowing journey of dangerous adversity! The characters are informed that some unknown adversary has disrupted an ancient tree called Wise Willow. This sends them first on a subterranean excursion into ancient tunnels infested with curiously ravenous Thri-Kreen! Then, they are introduced more formally with Wise Willow, who requires their services to cure her terrible plague! The players must then navigate the wild maze of her surface roots, purge it of grotesque creatures, and then find the cause of her ailment. Doing so excites the interest of the deities, Lathander and Sylvanus, who descend from the heavens in a glorious show of light and mysticism! The two divine beings then graciously bestow their gifts upon the party to reward their deeds.
For 6th - 8th level characters.
