#dainskirk

These are something I got

Dainsleif is an immortal being who retained his sanity well since cataclysm due to a ring from his brother

Sutralogi and Dain are co-students

Skirk is a.. humanoid being that able to withstand any climate and living environment, that's why her people was masaccred.

Both Dain and Skirk are hundred years old

Dain only seeking revenge and won't involve himself with people from the Seven

Dain was in pursuit of the sinners, including Sutralogi

Skirk has been avoiding people to retain herself as a "trespasser", she also said avoided Childe so he could improve better

Skirk is actually very gentle at heart but has strong resolution thanks to her master

Dain, surprisingly we don't know about himself better than Skirk

Skirk was on "pursuit" to surpass her master

In short, both Dain and Skirk has similar destination, albeit very different motives. The crossed destination: Sutralogi

Dainsleif often teamed up with traveler, who's in pursuit of their sibling

Traveler often crossed path with Childe who keeps trying to find his master

Dainsleif and Skirk in fact, already met but Skirk couldn't stand him lol

Skirk lives in a different flow of time than Teyvat (abyss) and she can play guitar

Khaenri'ah is a good defining objective/keyword for both of them

In my opinion we also need to understand more about abyss twin in order to learn Dain's past
