In one universe, Ty opens the backpack and the booby trap inside triggers an explosion, killing everyone in the party except Throg. In another, Ty raises the flap on the backpack to reveal a bizarre magic lock with a large slot in the shape of an axe-head; the party looks at the lock, looks at Throg's axe, and everyone sees that they match, while Throg whimpers, "No, no, no." There's also a universe in which Ty discovers that the backpack contains the fabled Hammer of Sigmar. In yet another of these parallel realities, the backpack slides out of Ty's grasp and unfolds into an arcane portal, leading into the realm of the enigmatic sorceress Lady Gaverzandendel: most of you perish, but those who survive obtain great power. And of course, there's a universe in which Ty finds that the backpack is empty. Finally, and perhaps most importantly, there's one where the backpack is full of these little triangular pyramid things. Very important, but that isn't this one either.
In our world, Ty opens the backpack to discover the following...
-10 loaves of Elf Waybread.
-1 Healing Potion (restores 1D6 Wounds).
-2 Glowstones (can be used as a light source, but will eventually extinguish).
-35 gold.
