Our first session went very well. The party was notified by the wizard, that there were recently uncovered Eladrin ruins fairly nearby, that may contain a large portion of undiscovered treasure. After a bit of party meandering around the plot and getting to know each other, they all finally agreed to go and visit the ruins. After failing a skill challenge to find them in the first place, they had to pay up a fair portion of their money. (Not even enough for one person to afford, they had to pool together.)
Once inside, the party all lost consciousness, and I played with each of them separately as the Mirror Trap each had them facing their personal demons. They all survived, though some just barely.
