That map is special, we are at a limit where jormag minions, primordius and branded could "cohabit".
Indeed: Destroyers in Mount maelstrom and Icebroods in Snowen drifts. (Branded where we are, Thunderhead peaks)
I noticed something when travelling through maps recently: Does an elder dragon avoid to corrupt minions already corrupted by another dragon? They are 0 map since the beginning where you can meet two types of draconic minions! And if it was the case, would they fight together? I don't think so but maybe?
But here is where I arrive: They are 0 branded asuras or sylvaris. Why? They are located on mordremoth domain. Whereas we can find risen asuras due to the pact presence in Orr. But then, who is corrupted by primordius? We never saw fire-asuras... oh wait.. asuras turn into destroyers when corrupted? That's strange. Argh it's easier with kralkatorrik! So now, asuras and sylvaris have more chances to become branded... ;o
