Biram

Biram is the current chief of the Masters of Night Wind. He has a progressive mindset, wanting to implement new changes but not to the point that it would destroy their traditions.
When the Traveler and Paimon first approached the Statue of the Seven in Tezcatepetonco Range, they were greeted by an Iktomisaurus that beckoned them to head into the village. Upon arriving, they were greeted by an Iktomisaurus Elder, who the tribesmen called Elder Tlapo. Elder Tlapo had a vision and designated the Traveler as weaver. Biram was notified of their arrival and explained Elder Tlapo's actions, while also telling them that he wished to decipher the "gift from the spirits" before his time as chief would end.
Biram tested the pair in escaping a space created by Huitzilin and was pleased when they managed to leave without his help. He then sent them to collect dyes to begin weaving the scroll, but when they attempted to make one, failed to do so. Biram was unsure as to what the cause of the failure was, but promised to investigate and let them know once new developments were made. Paimon asked him why the tribe didn't record on paper, and Biram asked them to follow him to the top of the village. There, they saw a massive graffiti, which Biram explained had been with the tribe since its founding and he could not simply forget about the past. He also felt that the tradition of weaving scrolls wasn't worth giving up and would try to find a way to produce them no matter the cost.

Biram is an extremely tall man, surpassing every other human in height.

While conducting certain ceremonies, he wears the Soul-Shielding Cloak, which is meant to resemble a Iktomisaurus. The garb is an important relic handed down by generations of chiefs. In most other duties, Biram does not wear the cloak, though he still retains his Iktomisaurus-like mask.

The nation of oaths situated in the western regions of Teyvat.
Guided by the flame, you pass through lengthy gorges and valleys to reach the land where the torches blaze, where all fires converge. Upon the blazing fields where Saurians roam, witness the end of the ancient war alongside the valiant warriors who resist the darkness.
Natlan is one of the seven regions of Teyvat. It is the nation that worships Mavuika, the Pyro Archon and God of War. Natlan is located beyond the west side of Sumeru's desert region, the Great Red Sand, from the Desert of Hadramaveth. It is also home to natural hot springs created from volcanic activity.[3][4] Its people are grouped into tribes, and each tribe follows different rules.[5] During Tenoch's era 500 years ago, there were at least six major tribes in Natlan, of which all are extant by the time the Traveler arrives there

The Masters of the Night-Wind, or Mictlan, is one of the six tribes in Natlan. Out of all of the tribes, the Masters of the Night-Wind have the deepest connection with the Night Kingdom. Their primary role is as "shamans" (or "mystics") who conduct rituals to communicate with the Wayob for knowledge and guidance. They are also responsible for monitoring the health of Natlan's Ley Lines and Phlogiston. Members of other tribes often travel to the Masters of the Night-Wind to seek their spiritual services, e.g., to read their futures or bless their tools and weapons. Their other areas of expertise include storytelling, record-keeping, medicine, and Phlogiston Engraving.
