With operations of dungeon coming to a halt due to the orc invasion from the west, Gorp the Dungeon Overlord must now travel outside the safety of his dungeon and finally meet with King Gilden of Hallstorm Castle. However, things do not go as planned and Gorp is captured by the orcs on his journey to the castle, setting into motion multiple events with uncertain outcomes for the whole realm. The orc forces are growing stronger and it is up to Gorp and his trusted goblin companions to find a way along with the humans and fairies to defeat them and become the Defender of the Realm.
