The Storm Gift "Insurgency" can turn an enemy building into a Temple during Conquest - even if it is a Chaos Nest.
What if there is already another building in the area with the Chaos Nest (be it my own building or someone else's)? Can I still Conquer the Chaos Nest and turn it into a Temple?
No. Only Chaos Nests can be in an area with another building. So, if there is already another building, and you Battle Chaos, you must destroy the Chaos Nest.
