Castle Gromgard Wilderness is the place where you retrieve the Red Minion Hive. The place is "infested" with pumpkins and halflings. It connects Castle Gromgard with Farmstead. You can only reach this place in Overlord: Dark Legend. You will have needed to find the reds and defeat jinks the halfling to be granted a minion pillar of 5 more minions. This in turn will allow you to push the barrier requiring 10 minions leading into the Farmstead area.
