Role in Plot
When Tucker, Caboose, Dr. Grey, Carolina, and Epsilon meet Santa, the A.I. informs them of the Communication Temple, it's location, and it's abilities. After hearing this, the Blood Gulch Crew and Chorus armies make it their goal to activate the temple and complete their mission of sending a message to Earth revealing the actions of the Chairman and Charon Industries. When the space pirates go to guard the temple, the Chorus armies, and Blood Gulch Crew confront and battle them in order to gain entrance.
The crew eventually make it to the temple's control and have a final confrontation with Felix and Locus, where the latter betrays Felix and helps the Reds and Blues kill him and activate the temple. After Locus disappears, Santa allows the crew to relay their message across the galaxy.
