The soaring towers of this isolated walled castle can be seen from afar, sweeping up like menacing black nailed talons reaching into the sky. It lays at the southwestern edge of the Troll Hills and north of the Winding Water.
The Crypt is a series of wizards towers, each standing in its own circular walled garden. The towers stand on the banks of a small spring that rises in the cellars of the highest tower and is much befouled by the discharges of the Shadow Rings experiments. Its luminous waters cast an eerie, flickering glow over the towers by night. Their walled gardens are surrounded by a gloomy network of twisting streets and abandoned houses crowded along the stream banks. In these streets and houses, lesser undead shuffle about. Over this dusty city leap many dark, railless bridge spans that link the garden walls and the lower levels of the towers. Skeletal giant bat steeds and stranger creatures sally forth from them to attack travelers who venture too near.
Most sages believe the Crypt, which is very old, was once a Netherese wizards enclave. The spells of archwizards, a small arsenal of magical items including Netherese power scepters of various sorts, rare or unknown elsewhere in the Realms of today, and infernal or fiendish magic of terrible power are all believed to be found here.
