On the last day of the year, three Guildmasters of the Endeesy Adventurer's Guild -- Ruthmin Tern the Assassin Rogue, Christopher the Paladin, and Lyra the Stars Druid -- were chilling in the Guildmasters' Lounge when seven driftmas fey popped through a portal, begging for their assistance. It turned out that Saint Usla, in charge of Driftmas, had been kidnapped by fire creatures.
The Guildmasters tracked the scorch-trail from the Driftmas Demiplane, to the Transitory Holiday Demiplane, to the Hoobynoob Demiplane.
They found (and broke into) a laboratory guarded by salamanders, where Saint Usla had recently been, but she (and the Professor, one of Hoobynoob's people) had already been stolen by disgusting creatures.
In the laboratory greenhouse, they found a construct named Sam, who was very concerned that Jaq the Gourd Duke, in charge of Hoobynoob, had been acting very strangely, including with this peculiar plan for Saint Usla.
They went to Jaq's mansion, where they were hired by Jaq to recover the Professor. Jaq's theory was that Neepkag the Bogeyperson, who had been in charge of Hangadh-Buain-Noiche before the Burning Hate took it from Asya and put Jaq in charge as the Incandescent Bonelord of Heckbound Night (long before Dalya took over, renamed it to Hoobynoob, and made Jaq the Gourd Duke), wanted to carry out Jaq's own plan, but to their own benefit.
(Jaq's plan was to split his two personalities -- the Incandescent Bonelord following the Burning Hate, and the Gourd Duke following Dalya -- putting one into Saint Usla, so that each could be in charge of their own holiday. The Professor had all the details, it involved a plant that had been grafted with black dahlias and orange lilies, which through the laws of similarity could split the two personalities if ungrafted, and then graft the orange lilies onto a sunflower, representing Saint Usla's Numiel.)
The Guildmasters went to the Bogeyperson's cave, defeated them, rescued Usla, and were declared Nice and deserving of many presents by Usla. They returned the Professor to Jaq, who now owes them an unspecified favor.
