Apart from the long and tiring climb up here, the rooms in the Astronomy Tower offer an almost unparalleled view across the Hogwarts grounds. Professor Antares moved into this office three years ago when he first joined the teaching staff, and since his initial furnishing of the room, nothing much has changed.

The walls are lined with big, solid bookshelves, overflowing with large books with incomprehensible titles. Even the space between each rung of the shelves is in use - papers and scientific journals are stacked on top of each other, and they have been squeezed and shoved in on top of the books.

At the other end of the office, large windows open up on the fabled vista of the grounds - the lake, glittering when it's sunny and brooding in shadows when it's not, and the eerie Forbidden Forest in the background. Each window has been adorned with a set of grass-green curtains.

In front of the windows stands the professor's desk. It's big, made out of dark wood, and one wonders what kind of tree it might have once been. Its imposing respectability is slightly marred by a set of colourful wooden trays trays on one side of it. They were obviously meant to help fight the mess (and a piece of paper pinned to one of them, with a heart scrawled on it, shows that they hadn't been Risu's idea), but papers are spilling over on all sides regardless. There's a comfortable chair with a high backrest for the professor to sit, with a much simpler - and probably less comfortable - chair in front of the desk for a student.

On the other side of the desk, in a miraculously clutter-free corner, one can see a pair of photographs in polished silver frames, each showing a smiling couple with their arms wrapped around each other.

One is of Risu's parents; the inscription on the frame reads Karin and Per Laelaps-Antares, Luleå, Sweden.
The other shows Risu himself and a witch with blond hair (recognisable as the proprietress of Florean Fortescue's) in front of a spectacular glacier.

Don't forget to knock!
