Anyone know the title of the BGM from T1 Myeongga?

Looking for the title of the BGM from the T1 Myeongga teaser and the BGM that plays from 2:54:34 in the T1 Myeongga outro.

I was blown away after watching the T1 Myeongga documentary yesterday, and after looping it a few times, I got hooked on the BGM. If anyone knows, please let me know!
