OH, one thing I forgot to show you guys, before we all go - I drew a map of the ruined cathedral to help me remember where everything was and where all the traps were. You guys actually missed the worst of the puzzles and deadliness 8D;

The purple dots are living stone beasts which come to life when the security system is activated via the dias. The red are mechanical traps such as the arrows and trapdoors, but the big floor full of red and blue in the middle is actually one giant puzzle room that, if done incorrectly, drops the heroes right on top of the dragon sleeping in the deep chamber below.
The pink splodges are magical traps, such as an incinerating trap, the Illusion of Heart's Desire trap, which wouldve caused a lot of confusion since our heroes wouldve already been separated by the time they reached it. The "Melting Trap" sounds horrible and I cant remember quite what it was meant to do - all I remember is that one of them was to be trapped in this small, apparently inescapable dark room which sealed upon being entered and bad things would happen if the others didnt get them out quick enough.
Again, hope you guys have enjoyed the trip! =D
