((BTW, by Valley I am referring back to the "Valley of the Dead" that you visited last time. So all the relevant details are the same. Here they are again in case you want to review them:
0. It was created by a duel between Abolar, the God of Fishermen, and Seneope, the First User [of Magic] (they were annihilated by the ensuing reality whiplash)
1. Over 1000 generations of Nobles, Kings, Queens, Concubines, Merchants, Warriors, Scholars etc. are buried there. It is the largest cemetery in the world.
2. There is only one entrance: a staircase that leads directly down into the depths
3. For every person buried (i.e thrown down the staircase along with all their possessions) a personalized tomb is created by the distorted reality and the body is stored appropriately
4. A map is then "revealed" to a "Seeing-Cartographer" through a dream, who then writes the map down and sells it to the ancestor of the tomb (i.e highest bidder)
5. Without this map, the Valley is an endless, ever-shifting, random sequence of rooms; a collection of chaos
6. With the map, the Valley changes itself to match the contents of the map (more-or-less; the Valley is fickle)
7. Anyone that steals from a tomb (even with a map) without permission from an ancestor, is cursed (or so its believed)
8. Anything can happen in the Valley; magic is so concentrated there that reality is less strict (+1 to max RT)
In this case, you have the map (or you copied it, the wizards don't let any documents leave their dens) but not the permission))
EDIT: Ninja'd by Giglamesh, yet this post should cover your action (unless you want more specific information, in that case you'll have to be more...specific).
