I've been working on a little modded adventure map made on a Plains island. It includes 2 houses, both of which have mob sensors to activate and deactivate lights in different rooms as the player enters/leaves. Each house also includes a lever that forces the lights to remain on if you don't want to worry about adjacent rooms in darkness.
I'm using the Aphorea, Soul Chasm, and Wired mods (along with a small host of other, tangental mods) to create this place. It's packed with secrets, including a "prayer room" that's meant to give major cult vibes!
There's also an entire Temple waiting for you to discover it's secrets to the South...
