I'm doing a war storyline, where Brindleton is going to be invaded by wizards. I already started building witch-related buildings in preparation, since I imagine they'll want to integrate into the neighborhood well.
I have the Broomstick Club, which is an old Victorian-style restaurant that has a secret room for witch meetings. There's a little retail shop that will sell potions and potion accessories. I might also build a little kennel with all the best-looking cats and dogs, so witches can pick out their familiars or just find new family members.
Aaand last but not least, I'm trying to convert 1 lot into the school, and five for each house. The House of Fire will have students that study Untamed, Wind will have Mischief, Water will have Alchemy, Earth will have Practical, and Void will teach the non-witch occults. They're all going to have Voidcritters as mascots, and luckily I have the decal stickers to decorate the lots.
