"Ladies and gentlemen, if you'd turn your attention to me!" There was a crackling sound from the opposite side of the teacher's desk, a flash of violet light and a tall, dark figure erupted from the floor. His body was composed of inky blackness, pure necrotic energy tamed and tailored to serve as a body. The head was a bare, polished skull with crackling red gemstones for eyes. The creature half slithered, half hovered over to the lectern and cast his sparkling eye-gems around the room.
"You may call me Mr. Raharait. I see we have a good crop of students here this year!" He announced, voice booming as though it came from the bottom of a tomb. "Some old," his gaze briefly roamed over Daten and Aniela, Chloe, and a few others. "And some new." Istra shrank in her seat. "You've been provided with basic copies of the rules, but as your homeroom teacher I'm going to give you a few other bits of advice, just to get you oriented." He was pacing back and forth in front of the blackboard, his inky body blending in quite well.
"While I'm sure you may be distracted by our academy's hallowed traditions, do not forget to complete your scholastic assignments promptly and to the best of your ability. My colleague in the history department, Ms. Lathotep, has informed me that she will be collecting limbs from anyone who fails her class in a manner that will defy regeneration." If it was possible for a fleshless skull to grin more than he was already, he did.
"You may rest assured that we will not interfere with your activities when they take place within the appropriate areas. But they will only take place within the appropriate areas and any offensive action taken against the school itself or against a member of the faculty will be severely punished. We are your educators and guardians but we are also graduates of its practices, either by proxy or in actuality. As such, we ask, nay demand, your respect and obedience. Do not break the rules or disrespect us. Use a little common sense. A few examples of behavior I would not like to see repeated," here he looked pointedly at Syphereon, "Being chronically tardy," His head turned again, this time focusing on Heithis. "Attempted or successful unsanctioned dueling, and of course..." His voice grew soft, almost seductive, as his laser glare roamed around the room, finally settling on Katsuo. Even without eyes, the blind earth-manipulator would be able to feel the demi-lich glaring at him. "Touching an educator's possessions or violating his space. We may give you warning. We may not. So please be courteous."
