I can enter one of the stalker rooms.. I have full stats and security so I at least have a chance of disarming traps. Which one should we do first?

While stalker rooms usually do 3 sanity damage, there is a -1 sanity area effect at the mirror room which might mean a total loss of 4 sanity and therefore mission disclosure...

For the other room we still need someone to deliver the crushed insignia locket to the jewelry repair machine first. That should be pretty safe to do, I would think. Any volunteers?

It would also be good if someone with full stats could deliver the circuitry to the elevator control panel as it's likely we will complete Fen's mission. You then might get bonus sanity which means you could do the mirror room for us...
