If the Berserkers gathered on a large scale for this purpose, traveling thousands of miles from the Frozen Wasteland to the Donau Wasteland for revenge, it seems a bit excessive.
"The Shieldaxe Dwarves also live in the northern kingdoms, and it's likely that this band of Berserkers has a good relationship with them, hence inviting them as allies."

"That's unlikely! The four pure-blooded Dui'gal consider themselves the four pillars of Aegean and wouldn't get involved in such trivial worldly conflicts." Although Richard still couldn't figure out what the Shieldaxe Dwarves were up to, he saw from the behavior of the Golden Dwarves, Wild Dwarves, and Silver Dwarves under his command that the pure-blooded Dui'gal weren't so trivial.
