Balahn was part of the army that Avad, Ersa, and Erend raised to free Meridian, scaling the outer walls and securing the Temple of the Sun. He was then personally selected by Sun-King Avad to be Daytower's commander and ensure the Nora were properly respected by the Carja there - specifically, to make sure the Sundom didn't provoke the Nora any further. Following reports of corruption in the Sacred Lands, Balahn sent a group of soldiers into the valley by the border to investigate. When the reports confirmed his fears, he sealed Daytower in an attempt to contain the corruption to the east.
Balahn is a firm supporter of Avad's reformed regime, believing that peace is strength. Balahn also appears to share Avad's respect for women, chastising his soldier Walid to address Aloy directly and show her the same respect women are afforded within the Nora tribe.
As a commander, Balahn is capable and reliable, showing genuine concern for his men and not making excuses for his mistakes. As commander of Daytower, he is acutely aware of the lingering animosity between the Nora and Carja, and does what he can to mitigate any tension. He carries himself with a serious demeanor, but is not above banter or lighthearted antics, playfully referring to Walid as "lunkhead".
- If Aloy returns to speak with Balahn after completing A Daughter's Vengeance, he tells her to offer an apology to Nakoa on his behalf and vows a complete investigation into Zaid and his men.
- Even after completing the quests he is associated with, him and Aloy can still act as though they are ongoing.
- If the player has completed In Foreign Lands, he will still finish a conversation by asking for information on his "missing" men.
- Despite apologising for Zaid's actions, following the player's completion of A Daughter's Vengeance, he will defend the man's honour if the player decides to ask about him again.
- He can also describe the Carja and Olin long after the player first asked about them.
