Looking at the "full" map of the crypt, it really seems like there must be yet another passageway that could be cleared beyond Ozzrel's chamber. Any way to get back there? Licensed Luny 10:34, 16 June 2008 (UTC)
the crypt[]
Actually there isn't .. that's just an artifact of the way the game uses exactly the same map for all crypts. They just show or hide different portions to make the different areas. On a couple of maps, the blocking off of areas was not even done correctly (like the crypt in the sewers), so don't rely on what you see on the map exclusively .. they are mostly correct but they never really indicate whether something is actually a "through" passage, or just a blocked passage.
the more reliable method is to inspect the wall within the crypt (or cave) and see if it looks like it is "Aardable", if not, there is not way to get through.
But as with anything there are no hard and fast rules ... the passage to Ozzrel looked impassable before doing the Buried Memories quest, but was open after, which directly conflicts with what i wrote above :) !
All I can tell you for sure is that I have tried many, many times and I firmly believe there is no way to open any of the areas that only seemed blocked on the map ... any map. Here's all the maps I have Game widow 13:09, 16 June 2008 (UTC)
