Beastgrave and Ogres. Sounds like a match made in heaven
via Bob over on War of Sigmar
Ogre will be the 7th Warbands (in order of discovery)
All the Warbands in this season should be Beast/Savage Themed as the fight happen in Ghur.
We will know the last Warhammer underworlds Season 3 warbands this week end (or earlier depending on GW).
