Has there ever been any intra-pantheon cooperation? Not just with orcs but in general? Also are there any gods solely there to combat The Abyss?
Sure, the pantheons generally hate each other but they'll team up against more deadly threats. The Human and Elven pantheon have united against the Giant gods, the Dwarven and Giantish ones once united against the Sluagh gods, and most deities have put aside their issues at some point in the past to battle the Abyss.
There are several deities out there who focus on battling the Abyss, none of them have big official followings since they tend to be very driven and demanding deities not suited for peaceful civilian worship, but all of them have militant or secret orders to do their will and are generally bad people to get on the wrong side of.
