Severus + open (multiples welcome!)
Severus didn't want to be here. Quite frankly, he didn't want to be anywhere in the hellscape that was a crowded social event, but Narcissa had invited him, so here he was, nursing a glass of wine and attempting to blend into the shadows. Literally. He was wearing one of his formal robes, but the cloth was still totally and completely black, a fact that sort of helped his efforts to disappear had it not been for his height. Severus could only calculate the precise amount of time he had to exist in public before he could leave without being rude to Narcissa.
He had about an hour left.
The few people who were brave enough to approach Severus in the meantime were almost immediately deterred by the look on his face. For the most part, though, he was given a wide berth, and for that he was grateful. It was the only time his reputation afforded him anything worthwhile, and it gave him space to reflect. Not on the exhibit, of course — he could care less about the oversimplification of Wizarding history — but on his lesson plans and the Wolfsbane Potion, which was still largely in development. He'd need to owl Slughorn sometime this week regarding his theories on an increased level of Ptolemy.
