This Ko-Metru Knowledge Tower is a base used by the Xal-Fettk Union, and is the main base of the Xal-Fettk. The base is nicknamed the Spire.


The Matoran curator that originally owned this tower put it up for sale for unknown reasons. It was quickly bought up by the Fettk Order, and the Xal Company gained partial controll of it in the merge. Soon, the Xal-Fettk Union had nicknamed it the Spire.

The old astrology towers were mostly salvaged and equipped with low-budget Plasma Turrets, lest their enemies decide to attack.

Much of the Knowledge Tower is now still in use by the Xal-Fettk, whose cunning minds use its data and information to plan their strikes and missions.
