My Kingmaker game has continued past the end of the AP and the PCs will soon be facing off against a powerful eremite overlord kyton. The adventure will occur on a demi-plane in a living tower built of bone and flesh.
I had planned on including a few "normal" eremites to accompany the BBEG, but I'm having some difficulty coming up with appropriate high-level encounters that don't involve kytons.
Please let me know if you have any suggestions, especially if your name is F. Wesley Schneider. :)
The PCs are currently 18th level with 6 mythic ranks. Mythic-specific suggestions are appreciated but not required. I expect the tower will have a trap or two and a few high-level encounters, in addition to the boss.
Also, in case it helps, I will include some background. Though most of it is germane to my home campaign, those wishing to avoid Kingmaker spoilers should probably not read this.
The Star Elves were originally a space-faring race that spanned the cosmos. There world had been destroyed by technology, however, and they reached out through the galaxy, to find another home. One of their ships approached Golarion but, unfortunately, their technology failed and it crashed into the planet’s surface. Life vessels jettisoned out, landing the Star Elves in Casmaron.
The survivors began rebuilding their civilization, swearing off technology and instead embracing magic. Their magical feats soon eclipsed those of other mortal mages and their civilization grew immensely. Unfortunately, they soon drew the attention of the Cyclops necromancer, Vordakai, who led a campaign to subjugate the Star Elves and steal their secrets. While powerful, the Star Elves were no match for an army of cyclops and they fled westward.
The Star Elves eventually came upon what is now known as the Stolen Lands. Here, there were no foes that posed a serious threat and the pristine wilderness provided an opportunity to rebuild from scratch.
It was during this period that Mourn Duskwalker arose as the leader of the Star Elf community. Mourn was a powerful wizard and was aided by a council of mages, with two immediate subordinates: Satherem Verdurous, known for his love of growing things, and Nostur the Ruminater. Satherem and Nostur frequently clashed in their philosophies and in their desire to gain Mourn’s favor.
For a time, it seemed that peace had finally come to this troubled race. After the passing of decades, however, rumblings came from the east and Vordakai once again turned his attention to the Star Elves.
Mourn Duskwalker, along with Satherem and Nostur, then discovered the Night Realm, a demi-plane contiguous with the Shadow Plane. The Night Realm seemed at first a perfect, tranquil place that could serve as a refuge for the Star Elves. As Mourn soon learned, however, this demi-plane is a prison for Count Ranalc. Once one of the Eldest, Count Ranalc had been imprisoned by the other rulers of the First World in the Night Realm.
Mourn recognized Ranalc for the danger that he was and attempted to flee. Ranalc, seeing a possible opportunity for escape, promised Satherem and Nostur great power. The two turned on their former master and struck him down, but did not kill him. Instead, they bound his vital organs in separate but linked alchemical containers that prevented Mourn from obtaining revenge but allowed them to pry further secrets from his intellect.
Ranalc fulfilled his promise, but in a (predictably) twisted and sadistic fashion. To Nostur, he gave the gift of death, teaching the Star Elf the secrets of lich-craft. Nostur now inhabits a ruined citadel in the Shadow Plane, which is haunted by the ghosts of his people.
Satherem, on the other hand, received the gift of “life.” Ranalc showed Satherem how pain is a path to power and, through horrific self-mutilation, Satherem was transformed into a kyton. He is constantly surrounded by a cloud of wasps and other stinging insects that use his ruined body as a host for their young.
Nostur and Satherem both now vie for the attention of Count Ranalc. For the last several millennia, however, Satherem has proven more powerful than Nostur and the kyton overlord now resides on the Night Realm. Shaping the plane-stuff of the Night Realm with his will, Satherem has created a monument to pain---he rules from a shuddering tower of bleeding flesh and bone.
Nostur has asked the PCs' help in destroying Satherem. There is a good chance that they will take Nostur up on his offer, who will send a simulacrum of himself and a half-dozen Star Elf magus vampires to help the PCs. I haven’t decided yet whether he will betray them during a key battle.
Thanks for any help you can provide!
