Nimril drank a healing potion, restoring her health, and walked along the bookshelves, examining the books. She tried to linger near the cabinets next to the desired door. Then, taking advantage of the moment when the old man wasn't looking at her, she slipped inside.

The old man didn't notice anything. After walking down the corridor, Nimril first found herself in a spacious training room, then entered a small, cozy office. There were some books on the shelf, and an open tome with a list of unfamiliar spells for the northerner lay on the desk.

There were several (3) pull-out drawers in the desk; at the edge of the room stood a safe, and on the other side was a bed with a portrait of some fair-haired woman and a little girl hanging above it.
