Divination (2 in 1)

Kieran visited Harvest Inn more than once.

One could even consider, from a certain aspect, that Harvest Inn was the place he was most familiar with in the big city other than his own room.

However, Kieran never entered the bar counter before, let alone the hidden room behind the secret door.

Following Rachel, Kieran went past a small door and the new environment isolated the merry atmosphere back in the inn.

Kieran sized up the border of the door, there were patterns carved all over it; a sudden realization hit him.

"Mystical runes to isolate noise and cause others to overlook any peculiarities?"

Pro level [Mystical Knowledge] allowed him to easily recognized these runes before him. It wasn't that hard for him to set up also if he had the required ingredients but Kieran didn't want to modify 13th Wallway to such a complicated extent.
