How to Align with Mathis Castillo in Starfield

To secure Mathis Castillo as your companion in Starfield, you must side with him during the "Echoes of the Past" mission. This mission is one of the initial Crimson Fleet missions, where you, alongside Mathis, Delgado, and other Crimson Fleet members, search for Kryx's last known location.

Should You Support the Crimson Fleet in Starfield?

Towards the end of this mission, Delgado, the leader of the Crimson Fleet, will inquire about Mathis's assistance. To align with your fellow Crimson Fleet recruit, express that Mathis has indeed been helpful in the mission. This response will convince Delgado to accept Mathis into the Crimson Fleet.

Failure to do so will result in Mathis being expelled from the Fleet and attempting to harm you later in the story.

How to Choose the Crimson Fleet in Starfield

The second prerequisite for recruiting Mathis Castillo is to side with the Crimson Fleet at the conclusion of the faction's final mission, "Eye of the Storm."

Throughout this quest chain, you'll likely navigate between the United Colonies System Defense and the Crimson Fleet. Ultimately, you must make your final decision regarding the fate of Kryx's Legacy.

Selecting the UC System Defense will lead to the Fleet's destruction. To recruit Mathis, you must deliver Kryx's Legacy to Delgado at The Key. This will prompt you to engage in a massive space battle against the UC, culminating in a raid on the UC Vigilance, with Mathis providing crucial support.
