Ossuary of Dread
From UnderlightWiki
Two great sanctums, stalwart and enduring, rise from the pit that encircles them. All around, the floor is littered with skeletal components, strewn throughout milennia but preserved amongst the silent pale cliff boundaries. A cool breeze clears the air, yet carries an oppressive aura of destruction and regret, along with the occasional clack of bone upon itself.
This plane is inaccessible to unsphered dreamers. It connects Lambent Flats to The Trinities.
Within it lies Lower Ossuary of Dread, which cannot be accessed by dreamers below second sphere.
