- For other crypts, see crypt.
The purpose of the crypt is unknown - it may be a playground for developers, a testing site of sorts, an unfinished instance, or something else entirely. It is interesting to note that using WoW Map Viewer you can see that the crypt runs under Tranquil Gardens Cemetery in Duskwood. This might play a role sometime in the future, or could be a complete coincidence.
This area used to be accessed via dying close to the gate and running through it, but this was changed in Patch 2.0. In Patch 7.0.3 the Well of the Forgotten was made available, and in Patch 7.3.0, the entire crypt was opened for all who solved an extremely difficult puzzle.
This section concerns content exclusive to Legion.
In Legion the Crypt is now partially accessible. It was renamed "Forgotten Crypt" and the first room is now fully accessible, with a wooden wall blocking off the rest.
Reasons for abandonment
Many players suspect that the crypt was never fully implemented because the mildly disturbing content, mainly the now infamous room of upside down sinners, would've made World of Warcraft's ESRB rating become M for Mature. On January 24th, 2014 Blizzard community manager Bashiok responded to a post inquiring to the reasons the crypt was never used and provided some insights on Blizzard's design processes back during the days of it's creation, stating the reason it was abandoned was more than likely that Blizzard simply changed their minds about using it.
- Patch 7.0.3 (2016-07-19): Subzone renamed from Crypt to Forgotten Crypt.
