The reception hall, and Edelgard first!

As Byleth headed for the stairs, Sothis teased in his head, 'So, it sounds like the other two Professors are going to be letting you pick the House you mainly teach. Granted, you will be teaching the others to a lesser extent too, but do be sure you pick your primary House wisely! And it also sounds like that cute mercenary girl is going to be joining the House of her choice as a student! Maybe you'll be teaching her too!'

Byleth rolled his eyes a bit as he walked down the stairs. 'I'll be looking into each House with the leaders, then visiting the classrooms they each meet up in. I'll make that decision once I have a better handle on the Houses,' he mentally replied.

'Okay, not a bad idea,' Sothis nodded in his head. '...just make sure you factor in which House has the most lovely girls too!'

Byleth paused, and to his personal dismay, found himself actually considering that. '...I'll factor it in, if only because your powers will be useful for getting someone I'm attracted to to pay attention in class if we have to resort to that. I'm still new to teaching, after all, might as well play every card I have available to me.'

'Fair enough,' she replied in his mind as he reached the reception hall.

"Byleth, over here!" he heard Edelgard call out to him, and he turned and approached her.

"Princess Edelgard," he replied, putting as much respect into his tone as he could manage.

"Just call me Edelgard, Professor," she nodded. "After all, I heard you are teaching here now. A pity, I was hoping you would lend your strength to the Adrestian Empire."

"I still might, albeit in a different capacity than you were hoping. I believe I'll get the first pick of which House I'll teach primarily, and I may choose yours. I'm still making that decision, however, so I thought I might ask you to explain a few things about your House," Byleth explained.

"Oh, of course!" she blinked, looking intently at him. He was sure he could see calculation in her eyes. That didn't unsettle him, she was after all, in line to be Emperor of the Adrestian Empire. A bit of shrewdness was practically required for that. "What would you like to know?"

Byleth considered. "I'd mostly like to know about what your House is known for, and any notable members?" he requested.
