Serpentine Tower
From Realera Wiki
The tower in Ankrahmun, where many studies of magic are conducted and where mages can visit the astrologer Tothdral to learn spells.
It is also known for its mysterious underworld, where monsters such as the Fire Elemental, Vampire, and Behemoth are trapped behind a wall, the former of which can be freed by pulling a lever a floor above. Even lower, you can see a genie trapped in the room along with some mysterious and strange items, such as Boots of Waterwalking or Carrot of Doom.
In addition, there is a small library in the tower, containing some books on magical experiences.
