Today was a special day, for it was Nathara's 11th birthday and the day her Hogwarts letter came. Severus came up to his daughter with a necklace in his hand and told her, "It's charmed to protect you from offensive spells, potions, and it acts as a Portkey to take you to my quarters or the common room. The activation word is ~Harmonia~". The last word was spoken in Parseltongue, but the message was still there.
Luckily, the family of four had already went shopping for Nathara's school supplies the day before, so, all Nathara had to do was pack her trunk. Then, something in her mom's sentence caught her attention. "Your quarters?" Nathara asked.
Severus grinned and a glimmer of mischief sparkled in his eye. "I'm the new Potions professor at Hogwarts and the Head of Slytherin House. Surprise, snakelet!"
Nathara squealed and hugged Severus tightly. She pulled away and said, "Now that you're a figure of authority at Hogwarts, will I be treated like any other student?"
"That's right. I want the other students to understand that you'll be treated no different than they will just because you're my daughter."
"I understand, Mommy."
