Chapter 3: Builders of a Legacy [Xenoblade Chronicles X Definitive Edition]

Vandham reports that a Skell that was being used by a Pathfinder team has broken down in southeast Primordia. He appoints Elma, Jason, and Lin to investigate the Skell and the Pathfinder team.

Upon arriving at the Skell, the party finds no sign of the team. Lin also notes that the Skell must have been wounded in battle, but the markings do not suggest wild animals. Lin then receives a Pathfinder signal from inside a nearby structure, but then detects numerous alien lifeforms. Elma notes the orderly, nonrandom nature of the lifeforms' movements, and deduces that they cannot be wild animals, but intelligent lifeforms.
They are subsequently confronted by two of these such lifeforms, revealed to be the Prone. After Elma tells the two Prone that she and her two partners are humans from Earth, the Prone immediately demand to know why she would be here. Elma realizes from this that they must have already encountered humans previously. The two Prone then attack the party, with the intent of killing all three.

After defeating Glennar, as they leave the base, they hear yelling from inside a storage unit nearby, as something is trying to escape the unit. The party suspects that it is another hostile lifeform, but nevertheless investigate, albeit with great caution. Suddenly, one compartment of the storage unit bursts open, spilling out several unknown items and a Nopon, Tatsu.

The party decides to take Tatsu with them to introduce to Vandham.
