I found it.

The person who created the barrier was Kim Jin-hyeon, one of the members who founded Goryeo after Wang Geon in the early Goryeo Dynasty. This person has also been rumored to be a 'guru' for some time, apparently it is the same person who wrote SCP-994-KO-g. There is another document left by Kim Jin-hyun, and it is being kept by the Kim family in Gyeongju. The book had all the information. How to contain SCP-994-KO, how to maintain the barrier, and why should SCP-994-KO and not SCP-994-KO-h be the subject of the barrier.

I think this guy's comments are quite helpful.

We bury our kin here. 
Because he wants to become a monster after the monster that killed him.
The following text was found in the 6th floor personnel lounge. This was written with the blood of Muho-17 crews on the floor of the break room. The original text written in Idu was translated into modern language.

Wow! Wondertainment [here/in this land] is dead.
