The Oakheart Academy for Wayward Girls - Part One

HEXENBRACKEN Hex # 03 05
Tucked away in the northwest of The Hexenbracken, you will find The Oakheart Academy for Wayward Girls.

The Academy was founded by Gristel Oakheart as a place for noble families to send their daughters of rebellious or otherwise undesirable disposition. The Hexenbracken was rife with witchcraft and dark sorcery. At the Oakheart Academy, the girls would be cured of any transgressive, mystical tendencies.

However, a dark secret lurks far beneath the dormitories and halls of the academy. Gristel Oakheart is high priestess of the loathsome Juiblex, the Faceless Lord and god of slimes, jellies, and oozes.

It is rumored that Gristel herself is using many of the students in evil rituals in order to create a gateway for the foul god to enter into this world. Many students have gone missing and there have been a  few who have left seek help from the outside. Most of these are brought back by Gristel's sentries or are devoured by the aboleths in the waters throughout The Hexenbracken.

Furthermore, Gristel has been performing experiments on students, as well as on herself, to create the perfect consort for Juiblex. Many of her experiments have resulted in horrific slime hybrid abominations that she keeps locked away in a hidden vault deep beneath the Academy.

GRISTEL'S VAULT

1. Prisoners and test subjects are magically teleported to this room. The doors to the North, South and East are locked. The west wall of the room is covered with several hooks hung with leather aprons and gloves. Several candelabras illuminate the room. On the wall next to the East Door is a lantern covered in red glass. When the lantern is removed, a switch to open the East Door is revealed. However, as it opens, an enormous black pudding (AC 6 HD 10 MV 80' (40') No of Attacks 1 3-24 dam SV F5) falls from the ceiling.
2. The floor of this room is covered in magical symbols that glow a sinister green color. Along the east wall are 8 metal amphoras sealed with wire and wax. Each one holds a virulent slime of varying hue. If opened, the slime will explode into the face of whomever is holding the vessel. Save vs. poison or die. 4d6 damage is save is successful.
   The symbols on the floor are actually carved into the stone and the greenish glow is from a green slime   seeping through the cuts and cracks. Anyone who steps on a symbol will be attacked by the slime. (AC 10 HD 2 MV 3' (1') No of Attacks: 1 SV F1)
3. This room is where some of Gristel's vile experiments occurred. There is a stone tub in the center of the room where a grey ooze (AC 8 HD 3 MV 10' (3') No. of Attacks: 1 2-16 dam SV F2) is working away at dissolving a bright white skeleton.
   The door to the South West is sealed and if observed closely, will seem to "breathe" and "bulge". If opened, a torrent of slimes, oozes, puddings, and gelatinous cubes will explode from the door, filling the room and slowly drowning and dissolving everyone it's wake. The twisting corridor beyond and stairway down are filled with the undulating, shapeless jellies of Gristel's creation.
4. Room of the Cubes - 24 Gelatinous Cubes (AC 8 HD 4 MV 60' (40') No of Attacks 1 2-8 dam + paralysis SV F2) routinely slither through this room and down the narrow passages that lead to Gristel's lair. Gristel throws rotting meat from the dining commons, and the remains of victims to her cubes regularly. Gristel can walk freely through the cubes without injury. 
5. Gristel's Lair - There is a 25% chance that Gristel will be in her lair - a room filled with all manner of magical equipment - bubbling test tubes, glass vials, stone amphoras, and in the South East corner of the room - a stone well filled with bubbling green slime.The door to the North West leads to another corridor that is filled with cubes, oozes, and slimes. Gristel is impervious to any of their damaging effects.
