Ah... I've committed myself to DMing a Planescape game at the local gaming club while I'm abroad. The game will be six sessions long, therefore I can't play the Abyssal Campaign there, therefore I've paused that while writing another (short) adventure. I'll upload the current draft of the Abyssal Campaign shortly after making this post (the only new bit is the introduction of Red Shroud, plus some minor reformatting and typo correction). While asking forgivance, I'll give ya the overall plot of the short adventure ("Matter of Opinion"), it's based on a nifty idea IMO. I'll post it if it plays well.
I don't think there's anyone on the boards that lives in Manchester UK and plays at the Nag's Head pub, but in case you are, skip the rest of the post or face certain doom.
Ok... the plot of "Matter of Opinion" revolves around an artefact which was forged in Limbo and does... uhm, nothing and everything. The Focus is made of chaos-stuff and it can take any shape and any power, depending on what the people around it believe it should do. This is wacky by itself, but Ssendam the Slaad Lord has nothing better to do than going around in disguise and telling people what this thingy does. And to everyone he says a different thing. So we have the githzerai, Shemeshka, the Xaositects, the Anarchists, the Guvners and the Harmonium, all convinced that the artefact is exactly what they need. And the bloody thing actually starts doing what they think it should do as soon as they get close, and stops doing it when the confused PCs drive them away. Xaos ensues. And then Ssendam wants his toy back. The adventure title naturally refers to the Focus itself.
I'll judge the quality of this idea by the number of players I can drive insane.
