The Serpentine Tower (here) is a mysterious place in Ankrahmun. It seems there have been spell studies on this place, and even today any sorcerer can go here to learn spells from the ancient teacher. There is also the White Pearl Quest on the ground floor. Underneath is a mysterious room, containing a Fire Elemental, Vampire and a Behemoth. The Fire Elemental can be released out of its room using a lever on the floor above. Below there is a room that is thought to be a joke of CipSoft. In this room are many strange items, including a Boots of Water Walking and a "portable hole". The portable hole appears to be one of the phases a SD rune or Death Strike takes as it hit the target. No one is yet to find out what it does. This room can be opened by using the switch underneath the Fire Elemental. No one so far has been able to free the Vampire or Behemoth, however, the Djinn that spawns down there and the 4 empty coal basins hold some thought. These 4 empty coal basins could be to do with the 4 monsters that spawn in the tower, but it is unknown.
On test servers players have somehow released the Behemoth, whether this is with Gamemaster co-operation or not is unknown.
There is also another lever located beneath an energy field in the room with the Djinn. What it does is still unknown.
This is the lever beneath the left most energy field in the Djinn room of the Serpentine Tower
The tower is located south east of the depot and up one level.
