The Second Visions

The party once again has an odd dream that interrupts their sleep. This one however seems to allude to the party's situation being more serious than originally perceived.
"Once again you have found yourself seeing odd visions, thought this time it seems you're not alone. First you once again see the flash of the odd mark you've each found on your bodies. Then you find yourself standing on the edge of a circular platform floating in an inky void, around the edges of the platform you see four other figures. Three of them you recognize as the strangers you previously found yourself with but the fourth is unfamiliar. Then your attention is drawn to the center of the platform as you see a glowing apparition of the tattoo appear once more, the sand in its glass falling. Then the faces of the same two men you saw previously. First is the older man, who's face is contorted in anger, then the younger man who's stricken with fear. Then a door appears, held shut by chains kept together with five locks. One by one each of the locks explodes, a crimson liquid accompanying the pieces of metal as they go flying. The image holds for a moment after the fourth lock breaks. Then it switched back to the hourglass as the last sands fall and the entire image glows red. It switches back to the locked door as the remaining lock breaks. As this happens each of you begin to feel a searing pain. Dart on your shoulder, Azarik on your chest, Gorky on your arm, Rexis on your wrist, and even Paathio you feel pain on your prosthetic arm somehow."
