Ashes of Empire
Officially, the prison at the heart of the island is known as “Fort Obsidian”, but the locals call it the “Ashe-Hole” in reference to it being one the worst prisons in all the Northlands.
The volcano makes itself known to those within, with hellish heat and a sulfur smell to match. Prisoners are routinely left to starve when their jailors can’t be bothered to brave the heat to feed them. Escape attempts are fairly common, but usually lead to a burning end when the would-be escapee gets lost within the maze of still active lava tubes.
It’s also a poorly kept secret that if you have a political trouble maker that you don’t want rabble rousing in your own prison that, for a fee, House Ashe will take such “dangerous criminals” off your hands. Such prisoners are tossed into cells so deep in the earth that they soon forget what the sun ever looked like.
