Assault Team's Entry Route

The Ocean Turtle is an autonomous megafloat craft that also acts as a base for Rath, the business front of Project Alicization, which is a top-secret plan to create a true bottom-up artificial intelligence. The giant pyramid-shaped craft has four Soul Translator machines in two special rooms that are used to connect to the Underworld. The STL Kirito is using to log in is located in STL Room Two.

In the center of the Ocean Turtle is the Lightcube Cluster, which contains all the artificial fluctlights, or souls, of the Underworld's residents. Gabriel's mission is to eject the precise lightcube that contains Alice's fluctlight so it can travel down the air tube to them.
