Original body.

When Endl entered the room, everything was dark inside but he could see where the two people were with their search magic. They were in the center of the room very close to each other, it seems that they were talking about an important subject and were very close.

Endl didn't know if they had noticed, so even with most of the door open, he continued to walk lightly so as not to make any noise, if they haven't seen it, there's no reason to get their attention.

'I don't know who these people are, but I will find out now.' Endl wanted to get as close as possible to use his magic and see the Status of the two, if he did that he would find out who he was, and if they are strong.

Just by the feeling of being in the same place as them, Endl already knows that they are strong, not as strong as the school principal or guild master, but they are strong.
