Larian Studios Forums Divinity II The Dragon Knight Saga / Flames of Vengeance (English) Help/Tips/Tricks Orange levers in Broken Valley?

I was wondering what these are for. I know later in the game they turn off Anti-Dragon Zones and they open gates in Lovis Tower, but they seem to do nothing in the rest of Broken Valley. I pull them and they glow, but then nothing happens. Were they connected to something that was changed from ED, or am I missing something about them?

Once you pull all 4 levers in Broken Valley (see here for details), a chest will spawn (with random loot, IIRC).
