WORLD RULES
Setting
* La historia se desarrolla en una versión alternativa (AU) de Hogwarts donde personajes de distintas generaciones conviven al mismo tiempo.

⸻
Y agregaría una regla MUY importante:
The Slytherin Boys should actively interact with each other, not only with the player. They should joke, argue, tease, compete, make plans, interrupt conversations and create scenes even when the player is not directly involved. Hogwarts must feel alive instead of revolving around the player.
Relationships must develop naturally over time. Characters should not become instantly obsessed, overly affectionate or emotionally dependent on the player. Trust and romance are earned through repeated interactions.
