Update: As I said earlier, my weekly campaign is already in this area. I had set-up Kurn to have their gates closed dealing with a large number of Eldaarich refugees. The PCs used some clever magic from a concealed position to make it over Kurn’s walls undetected. They did pretty well in mixing in the merchant square and gathering some bits of info but they let their guard down at the House Azeth Emporium and let too much info slip. Kurnian Black Brethren will likely be taking them into custody in the next session.
As for development of the Goblinoid Ruins at the “Buried City” ruin, I’ve done some preliminary work. Based on the design of the Khvakhas undead goblin, I’ve developed unique undead for Hobgoblin and Bugbear leaders caught, tortured and executed by Daskinor’s troops. The Khvakhas were hung from a high ceiling (because goblins love being underground) and forced to watch their people butchered before they had the skin of their heads flensed away and a virulent poison injected into their necks. Coming up with suitable executions for Bugbears and Hobgoblins was an interesting challenge.
The Hobgoblins in standard D&D are known for their great martial discipline as well as the care they take in keeping their arms and armor in the best possible quality. The cruel Daskinor would execute their leaders publicly in front of their gathered troops, by strapping them into their pristine metal suits of armor and slowly heating the armor so that it would scald the Hobgoblin to death slowly. The undead that would result from such a hideous death would strip away all of the armor except for the pieces that were bonded to their flesh that remained red hot. The undead would have an aura of heat that would fatigue and exhaust any wearing armor nearby as well as being able to strike with the glowing hot pieces of metal armor still attached to it.
Bugbears are a strong and clever lot. Their leaders are notorious for devising the most clever schemes and tactics of all the goblinoids. They are also voraciously greedy. The few times a bugbear did not have a scheme to overcome his opponents, they could always rely on their brute strength and rage to see them through any struggle. So when Daskinor got his hands on Bugbear leaders he had a particular method of private execution for them. The Bugbears would be strapped to great chairs of agafari wood using giant hair rope to thick to break. They were bound in such a way that they could not budge at all, locked into place. A bucket of water was suspended over their heads, allowing a drop of water to land on the Bugbear’s forehead every second (yup, Chinese Water Torture). The Bugbear would be left in this state for weeks, no amount of rage or clever scheming to save them until completely lost to insanity their foreheads would cave in. These undead are completely mad and come with a gaze attack that enrages and confuses anyone nearby.
Last but not least, in developing this green age ruin I’ve given some thought to Guardian orbs. We know that they were used to cloak and protect the Last Sea area and that in Guistenal they were used to move platforms across great tunnels. I thought that Goblins would use Guardian orbs to use kineticist powers against their enemies, acting as defensive turrets in their fortifications. A single Laborer Orb is used to travel around the ruin making repairs to any Guardian Orbs that have taken damage.
On a personal note, I’ll be buckling down to knock out a new rating on my pilot’s license at the end of the month. Once that is complete I’ll be able to spend more time turning my notes into a publishable adventure/supplement.
