Main chamber

The main chamber is filled with chests surrounding an open sarcophagus. A hidden (DC 10) locked (DC 20) door on the north wall opens to a second room. Opening any of the chests or unlocking the door to the Workshop (see below) will trigger an ambush by a horde of undead. Your party won't be  Surprised, but will be inflicted with the  Spell Rot curse (undead, such as Astarion, and wizards of Necromancy school will not receive this condition; climbing on the pillar in the north-western corner also removes spell rot temporarily). Spell rot causes each character to take 2d6Necrotic damage per spell level every time they cast a spell (cantrips don't trigger the curse). The curse will be removed when you leave the lair. While the curse can be removed using Remove Curse, it only removes it for 3 combat rounds (or 18 seconds out of combat) before being re-applied.

Workshop

The locked (DC 20) door hidden in the north wall can be revealed with a Perception check. It leads to a workshop with a chopped up body and a dead half-elf. The Jar of Mystic Carrion's Brain is found on the central table, while Jar of Mystic Carrion's Liver is in the locked (DC 20) Gilded Chest. Destroying either of the jars will cause a large explosion dealing 8d6Fire damage. Reading the book Funerary Jar Form and Function on the nearby table, you will find out that Mystic Carrion has hidden his heart in a zombie (Thrumbo).

A ladder to the north of the workshop leads back to the Undercity Ruins in a small previously inaccessible room north of the Voiceless Penitent Bareki.
