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 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, including stories of Andrius, the Wolf King of the North and Dvalin, the Dragon of the East.
He appears to be a curious person, questioning how someone as diligent as Jean (Genshin Impact) is able to press on so tenaciously, and insists that he will find the answer to his own inquiry. He also notes how Zhongli's placid attitude towards the fall of Morax as interesting, and wonders if Zhongli could be a player in the Rite of Descension. To his own theory of Zhongli, he persists on waiting, for he does not "lack time". In "Bough Keeper: Dainsleif", his curiosity is all the more evident as he requires three answered questions from the Traveler regarding recent issues concerning mortals and deities, along with 500 Mora, in order for him to become available as an ally of the Traveler during particularly difficult commissions regarding the Abyss Order.
Although Dainsleif detests deities that side with the Seven and dislikes the adepti for signing contracts with Rex Lapis, he has great respect for those who are hard at work, such as Ganyu (Genshin Impact). He also greatly respects Diluc Ragnvindr's unwavering attitude when it comes to protecting Mondstadt, but wonders if his resolve would stay the same if Diluc Ragnvindr 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 (Genshin Impact) 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.
At one uncertain point in time, Dainsleif desired to take fate into his own hands.
