En Argentis (Japanese: エン・シルバー, En Shirubā, En Silver) is a High Entia NPC in Xenoblade Chronicles. She is the sister of Zel Argentis and the daughter of Don Argentis. In Alcamoth, she can be found due south of the Fountain of Hope, standing by the flower bed around the edge of the large fountain.

She can be found in Tephra Cave only during the quest Stopping the Elopement in which she is involved, and can propose an unique trade there.

After the Mechonis Core event, if she has not been migrated to Colony 6, she can be found underneath the Ether Plant in Eryth Sea, hidden away on the cliff at the westernmost edge from about 20:00 to 03:00. An easier way to find her is to go to the escape pod, and set the time to 18:00.

Inviting to Colony 6

  • Housing must be Level 5.
  • Don Argentis must already have immigrated.
  • Zel Argentis must be registered on the Affinity Chart.
  • Recruiting her means that Zel Argentis cannot be recruited.


  • Zel Argentis
  • Don Argentis
  • Peppino (Only if they both emigrate to Colony 6)
