I have a question about the magic item, Horn of Valhalla (pg. 477). Are these wild Berserkers magical beings like spirits, like those old ghosts who fight for Aragorn in Return of the King? Or are they actual men who are somehow magically just dropped in the middle of wherever the horn is blown, and immediately content fighting for their caller?
I know that the ones called in the Runegraver ability are of course real men from their description. But the Horn of Valhalla seems to work immediately, and the mention of the berserkers “fading” after combat further leads me to believe them to truly be arriving from Valhalla.
