Points of interest

 * This isn't a big location: The central throne room is where the Death Guard fanatic has established his lair, gathering various valuables and other baubles. He drops the Reckless Brigandine. Oh, and there's also undead all over.
 * In the center is a Sigil of Atrophy, which applies Curse of Atrophy (-2 Might, stacks up to 5 times). Destroy it from a distance, or use a Sigil of Atrophy Wardstone to mitigate it's effects. There are traps surrounding it which causes it to attack if stepped on, these attacks cause Serious Burn (-2 Dexterity, -3 Burn Armor Rating). When the sigil is destroyed, the traps are deactivated.
 * Upon leaving the catacombs, you get to name the island as part of Mapping the Archipelago: Tikawara.
