Dainsleif is a man of mysterious origins but claims to have knowledge of fate itself.

Dainsleif is the former knight captain of the Royal Guard of Khaenri'ah. However, he failed to prevent the destruction of Khaenri'ah 500 years ago. A curse of immortality was placed upon him so that he would forever wander Teyvat.

Dainsleif is an enigmatic character who claims that his memory has "all but faded," yet is seemingly able to vividly recall the events of the Fall of Khaenri'ah. Additionally, he is also somehow able to recall many of the events that occurred in Mondstadt from thousands of years ago.

He appears to be a curious person who sometimes insists finding the answers to his own inquiries.

Although Dainsleif detests deities that side with the Seven and dislikes the adept for signing contracts with Rex Lapis, he has great respect for those who are hard at work. He also greatly respects Diluc's unwavering attitude when it comes to protecting Mondstadt, but wonders if his resolve would stay the same if Diluc were to experience the same disaster that he had witnessed himself; the fall of Khaenri'ah.

While indifferent to most crises, Dainsleif states that he would not tolerate the dangers posed from his former homeland, as he is only interested in opposing the Abyss Order. Likewise, he is particularly wary of Albedo due to his knowledge on the Art of Khemia, a form of alchemy that brought ruin to Khaenri'ah, and would personally intervene if Albedo made a single mistake with it.
