Risu hadn't managed to locate a helpful House-elf, so he had been left with levitating his trunk up seven floors himself. He'd just had time to move it into his office before it was time for the feast to start. Quickly switching his travelling cloak for a slightly more festive set of black robes, he hurried back downstairs through deserted corridors that would soon be filled with students again.

When he reached the Great Hall, he noticed he had his robe on back to front. Twisting it around awkwardly, he shuffled past the long table, greeting his colleagues cheerfully. "Good evening, good evening... How do you do... Risu Antares, Astronomy. Nice to meet you." There were a few new faces. Some of the students had joined their teachers at the table already too, and Risu nodded at them with a smile, struggling to get his right arm into the right sleeve.

He shrugged his shoulders, and the robe settled around him as it was supposed to just as he reached his seat at the far end of the table. With a contented sigh, he sat down, finally able to wave at the assembled students.
