Aleryon is bigger than Dandereon and considered one of the only "safe" islands in the Badlands. Much like the Black Forest of Silvanus it is completely forested with tall, blackened trees as if they had been scorched by a great fire. The entire island is completely silent, not even the sound of the nearby waves penetrates the thick trees.

Thorown, named after and by the Demon Lord himself, is the largest of the islands. It is covered in high, spiked mountains and filled with steam filled valleys. It was where Lord Thorown held his lair, and the ruins of the dark castle are still on the island. Dark creatures prowl the island and the large birds nest here.
