Archon leaded back in his staff chair, placed directly in front of the Slytherin table at the staff table, so he could keep an eye on his students as he ate. He watched as the students in his House whispered and pointed and made comments about the other Houses, probably planning things as well. They always were planning things. He couldn't exactly claim he was without blame- he didn't exactly teach them not to. His rule on the Quidditch field was simply "If I didn't see it, it didn't happen." But thank god none of them had noticed the interaction between him and Holiday. He would never have lived that down.<br/><br/>He shot a quick glance down the staff table, touching the silver flask in his cloak pocket. A week before school started, the Headmistress had come to him and requested that he brew a special tonic, one designed for vampires, to allow them to feed from unintelligent species and resist the urge to sink their fangs into wizards or Muggles. He could only presume that one of the new staff was a vampire... Fascinating. The potion, of course, would leave him or her lethargic and not at the top of his or her game, but it would lessen the danger of a vampiric mentor getting loose in the building and drinking from students.
