**Scene: Snape's Office**
**Snape:** "Sebastian, what brings the richest man back to a small teaching role at Hogwarts?"
**Sebastian:** "To make Slytherin great again!"
**Snape:** "Tell the truth..."
**Sebastian:** "To make Hogwarts great again!... Come on, Severus, put that Veritaserum away, you're no fun!"
**Snape:** "Tell the truth!!!"
**Sebastian:** "It's all true, but... I also want to make wizards great again!!!"

**P.S.:**
1. The protagonist is a Slytherin graduate, a friend of Snape, and not very fond of the Marauders.
2. The story includes an original female lead as a supporting character, with no sweet romance. The male lead is focused on his career, and there are no children for now.
3. The narrative highlights Slytherin's wisdom and ambition, with less emphasis on bloodline.
4. It contains secondary settings.
5. The timeline begins during the Weasley twins' second year, a year before Harry and his friends enter school.
6. Warning: This is the White Dark Lord, not the Black Dark Lord!
