Alvina was rushing around setting up last minute preparations when she felt the magical barriers of the sub realm they existed in being pulled, She felt the student entering into the protective barrier that was Caldwell's Academy. "Oh no" she would say to herself looking out the great window of the spire, where she had chosen to set up one of her many classes she would teach. She knew she would not have time to run down the stairs and she really didn't want to reveal what she was just yet. 
"Omeni Distras" she would say softly, using vocal spells had always been easier for her, though in her Draconic form magic would flow through her like any other being of magic, She would disappear from the class room she had been working in and appear beside the Head Mistress. 
"Greetings" she would say with a warm smile, and a soft lilting voice, Any that had not dealt with a dragon of her typing before would find her voice to be soft sweet almost angelic but somewhat alien as well, as it did not relate to any of the known accents of earth. 
"I am Alvina, Lady of the wind" she would say which is what Dragons would call their teachers.
