It serves as a scientific research center for the combined Babylon. It is the location in which the Babylon Sisters were created and developed. The Laboratory itself is divided into several different buildings, each of which is responsible for different a function or creation of a different product. In many aspects it is considered to be an advanced version of the Alchemy Building, and is capable of producing more materials then it's counterpart.
The teleportation circle for the Research Laboratory is located to the southwest of the continent near the Kingdom of Iglett, hidden in a underwater cave close to the island itself. The puzzle to activate the circle itself is actually complex.

The actual puzzle itself involves a series of slide puzzles that when completed triggers the activation of the teleportation circle.
