When working out the key elements of the DDC game I occasionally come up with events and encounters that don’t end up seeing the light of day. Sometimes I recycle them and sometimes they sit in my DNDBeyond encounters list becoming less and less likely to get used. In the spirit of giving some inspiration therefore, I sometimes write them up in general terms for people to use or avoid depending on whether they see it as an idea or a warning.
In this case I had an early idea that the group might stumble upon someone working for or with the trolls in the middle of negotiating with potential allies. In this version of the timeline I hadn’t quite worked out the dynamics of the Circle of Rot or its driving principles and so the back story to this was one of attempted conquest rather than a nihilistic drive to consume and destroy.

The inspiration for the scenario came from a map that i downloaded from Reddit from a post by u/Dreadmaps and was a large bonfire in a graveyard. I did some lighting level work in Roll20 to add wall boundaries and light sources once I’d uploaded it and put the player tokens in the top left corner as a default ahead of any actual encounter.
The concept was that a Tiefling druid working with the Circle, backed by some mutated ogres, would be trying to recruit a hill giant and his pet manticores. The group would have a chance to overhear some of the villainous plans and then either interrupt or sneak away from the scene, depending on how brave they were feeling.
As it turned out, the DDC hasn’t adopted a strategy of creeping about the valley in search of creatures to slay, and the concept of the trolls co-opting outsiders didn’t ring true with the way the group was experiencing the story either. As a result, the encounter has languished and been overtaken by events and power levels. I may throw some variant of it at them as a random encounter if play allows, but otherwise I throw this open to the floor.
The antagonists, if you want to build it for yourself, consisted of a CR2 4th level Druid, 4x CR2 Carrion Ogres (essentially ogres with carrion crawler heads), 3x CR3 Manticores, and a CR5 Hill Giant Sergeant. It was aimed at being a Medium difficulty encounter for 5x level 13 adventurers rather than a grand battle royale.
