Quickly you grab for the sides of the sarcophagus and pull upwards, dragging your exerted legs away from the groping tentacles which reach closer and closer. One brushes against your flesh as you clamber out, and you feel a horrid burning sensation.
Heaving yourself over the lip of the tomb you crunch into the chamber's mosaic floor, and roll over. Looking down, you see that where the thing touched you the skin is reddened and swollen, with tiny rents in the surface.
Getting to your feet you find that the black arms are stretching out from the tomb, blindly waving back and forth but getting closer to you. You back away and try to work out what to do.
