The Anvil Isles are the barrier islands of Blackbone Isle, keeping it safe from all a manner of prying eyes, and ship-sinking storms. They are primarily grassland and new forest, but feature well built fortifications. Constructed of stone, wood, and long grasses, they are fairly advanced for the skill level of the beasts that made them.
The Imperium once held rule over the Anvil Isles, but they have since fallen into disrepair since the start of the Maelstrom Conflict. Now, ruling over the primary island is the fearsome Pirate Lord Razorback. He has organized his pirates well enough to have a strong hold over the islands.
