2 hour Oubliette

The story is that 6 of you were captured and have been eeking out an existence in a 20' x 5' Obluiette for the last 3 weeks, your brutal captors have stripped you all of any items or clothing worth having, but 'Simon the Elder' has come up with a plan. Within the 2 hour time slot that he has managed to unfold, you four, the most physically able, will temporarily escape from the Oubliette into the Tomb below, you must find the Elder's green slippers, he says they will invigour him with supreme magic, you must return within 2 hours with 2 health potions for him, as his illness will inevitably overcome him, Winifred the LizardLady is even older than Simon, she looks even more perilous than him, it's doubtful she will survive even the 2 hours. At 2 hours the outer door (on the surface) seals shut for another year and that'll be that! GOOD LUCK!  Find the green slippers, return to the Oubliette with 2 health potions and do it within 2 hours! THEN THE REAL MISSION BEGINS!
