As have been said it is a classical plot and probably one that the elder GMs here have tried variants of. Jules Verne and his Captain Nemo as well as the recent Pirates of the Caribbean films do come to mind.
As for the dungeon itself: It is obvious that you put much labour into this. It is well written and very interesting at times. However I cannot escape that feeling of deja-vu. It all feels so predictable... A series of fights so the party can get treasure. A big nasty Pirate Captain and his pet Crocodiles.
Regardless: You have done well and the Citadellians obviously cherish your work. Congratulations! Go to Comment
Deja-vu can't be helped. It's an olde skool plot that kinda follows a predictable formula. I tried to punch it up with the mad prisoners and Threll the thief, but it's mainly meant to be a well-done classic dungeon. Go to Comment
Surely there will be legends of curses connected to precious stones - but there are always some.
I definitively like the deity, and the curse that it sent on enemies of ist people (note that the curse is not even terribly powerful, it may be more of a minor spirit, than a true deity). Those that wish to remove the curse have to destroy, or sacrifice all the diamonds (it is not easy to part with them though), or perhaps help the Sekkitans to reclaim their island and continue their life. An alternative would be to find through research the night when the curse strikes, and simply avoid looking at it (that may be hard too - human curiosity and love for the diamond are hard to overcome).
A blood diamond could even bring luck to a Sekkitan, if it is held for the purpose of later sacrifice.
Nifty idea. I like the description of the history of the diamonds. I also like the curse. These diamonds could make a nifty tool for assassination, assuming someone knew the secret. And sooner or later, everyone is going to forget Seenu, so no one will have a clue what's going on. Go to Comment
