Octavius had been at headquarters for a large part of the day, setting up an office there for The Quibbler. Dumbledore had thought it might be better for them to operate here, though they couldn't move their printing machines just yet, as they still hadn't told Xenophilius exactly what they were up to. That was a worry for another day, however, and he smiled as he hung his university degrees on the wall above his new desk.
It was a nice sized room in the back, set up with everything they would need. Three desks, one for him, one for Hermione, and one for Luna. There was a large cabinet filled with quills, ink, and plenty of parchment, all the things they would need to get right to work. Dumbledore had even been so gracious as to get them a coffee machine and a self-heating tea kettle, both of which would be used and often.
He was surprised when he heard someone call out, calling back as he assumed it to be Hermione Granger. Dumbledore had said in his letter that she'd be by today, and it was about time. There were important things to discuss.
