This is a really interesting plot, and a good possible prelude to another adventure featuring the mad emperor. He may not accept their story if the PCs return the gems (what do they do anyway? Item submission maybe?) Plus, the fellow is setting himself up to be deposed. Maybe the PCs get involved in that? Go to Comment
Thanks for the comment. It's up to the DM really, how it goes forward, the emperor might believe them and perhaps give them another task of some sort, but actually he might get pretty suspicious when the PCs return the gems so fast, and that may lead to a scenario or two.
And if you decide to add this to a campaign, then remember that the emperor is losing his sanity, and the peasantry will no doubt hear about this when time passes. Then the rumour will wander into other nations. There's another plot.
About the "deposing". The PCs might get involved yeah, if the peasantry creates some sort of a rebel faction. In fact, they almost have to, because they were the ones who returned the gems. You must remember though, that Madvar has a pretty big army and the emperor is a careful man, and pretty intelligent, although almost mad. Go to Comment
Yes, there is, but I think it's better suitable for regions, not for whole worlds. Well, it would be too much work to ONLY move Apierta (part of my world) here anyway. But, maybe some day... Go to Comment
