Abstalar nods. There once was a smugglers tunnel system that ran from beneath the glassworks to Junkers Beach. It was off that tunnel system that a temple to Lamashtu and a font for the creation of Sinspawn were discovered. That was sealed off though . Far too dangerous to have access to creating monsters with a vial of blood.
Later a sinkhole collapsed just south of the Garrison. It allowed access to a deeper ruin that could turn the 'Old Lighthouse' Into a weapon that fired magical beams. It also had The Labyrinth of Sin, with seven separate areas for each of the deadly sins with a servant of Lamashtu, The Scribbler, running amok in the Labyrinth. 3 years ago, we finally finished filling the sinkhole as that Ruin was sealed off as well. That one went very deep. As of right now, this tunnel network is all there is, as far as we know.
