I'm getting ready for another series of adventures in my current RQ campaign.
The setting is based on a mixture of Glorantha, Questworld, numerous random 3rd party fantasy stuff (Harn, Lum and Vecna from AD&D lore, Sanctuary and the Ranke Empire, etc), and a ton of original material we've added over a few decades.
Dorastor in our world fell into a sub-plane during the Arkat wars. There are a few planar connections, two of which enter on our plane. One in the Lunar Empire (of course!), and the other was opened up when a Demon broke the world near the kingdom that the adventurers currently call home. That one opens up in the mountain north of Forth Wrath in Dorastor and the entrance on this end is a huge chasm surrounded by miles of broken lands. The kingdom has built some defensive fortifications along the chasm itself and a small keep/village about 10km south (closest point where people can actually kinda live off the land). These defenses were tested recently when Ralzakark sent a pretty decent sized assault force through to their "side", resulting in some significant damage and lots of fighting. Some player adventures occurred as they attempted to stop scouting parties of the bad guys from finding routes around the kingdom's defenses. Also they learned that some Bat cultists have re-appeared nearby, which may lead to some other "bad things"...
Meanwhile, one of their enemies to the south is taking the opportunity to move on them. Well. Not so much "opportunity" as planned. A previous group traveling through his lands "accidentally" saved one of the sons of their enemy. Oops. Turned out that he seems to be a nice guy (demon weapon notwithstanding). He was being hunted by some creatures that looked like semi-formed broos (no horns, but otherwise broolike). He mentioned that his brother had sent him off to patrol the area when his squad was attacked. Hmm.... Could there be a good brother and a bad one? Nah.... No plot plan here.
The boo creatures are actually the result of experiments on criminals (and the good brother thought that his father was doing something right what with the recent reduction in crime...). A Thed advisor from Ralzakark is conducting them and working with the ruler. Of course, his attack was supposed to be a distraction for Ralzakark and not the other way around, but bad guys don't always work well together...
In the midst of all of this, the party will have to deal with roving broo creatures, figure out what's happening, deal with a couple random nasty things that have nothing to do with the main plot, but will put them in the right locations to get them information they need, try to help the good brother while stopping the plots of his father and brother, and otherwise get themselves into as much trouble as possible.
Hah. And that's just the backdrop opening stuff for a much larger and longer story arc I'm working on...
