The east of the castle is composed of three underground floors. Mad Scientist Treglow should be in B3. For now... enter B3 and check if Treglow's room is unlocked.

Accept

Then I'll leave it to you.

If it's not open, then next... Oh, I'm sorry. I didn't end the communication. I'll contact you again afterwards.

I have several books that Treglow lent me. I remember he wrote how to seal and unseal doors chemically that he's quite proud of. Please wait. I'll contact you again after I confirm.

Decline

I'll wait if you need to prepare.

(You tried to open the door to Treglow's room, but it wouldn't budge. See what Edea has to say.)

You can't open Treglow's room? I see. Treglow locks his door to secure his experiments. It looks like that habit persists.

Thinking of how Treglow is, the door isn't closed by physical or magical means. He used chemicals.
