I like this idea - a decent reason for a dungeon to exist. And loads of fun all around.
The only weak part is the assumption the PC's are master builders. :)
A nifty little encounter.
An interesting Idea that I had also used - though I had not seen this post at the time.
A good basic idea that could easily be broadened into a great adventure!
A decent adventure start.
I agree with Pieh on this one. I like this as it could be a campaign affecting incident - religious schisms are frequent drivers of conflict.
Collections agents - now that could be a good job for a bunch of PCs - having to walk the fine line between legitimacy and larceny.
I think combining Strolen's with Ria's suggestions would make this more generally usable.
A good starter for an adventure, for any timeline.
An interesting concept, reminds me in of Nim in a fashion. While not an extensive sun in itself, it opens the gateway to a great wealth of possibilities.
A nice start, but I really would like to see more.
I completely concur with ephemeralstability Go to Comment
Great simple starter! Right ready to go!
I think this needs to be finished - it seems incomplete.
