i had two main goals with this one. I also think that Kessandria is an underused niche character that diserves her spotlight. She should get some chatacter and feel very powerful and frightening.
I also wanted to put stuff to use that is available like find a meaning for the translucent monsters or for the fact that you could remove the covers of the tomb.
Kassandria had a few more tricks up her sleave in the original longer Version of the quest. The 2 doors that lead to the corridor 1 were magic doors. It was actually just one door ahe could switch places on zargons door. So if the heroes tried to rush to the first door it would disappear and be placed in the other room. Then there would have been wild discussion what to do under the time pressure. Split up the party or send someone through the wall to stop the monsters 😀
