The location described here is an underground throne room with its adjoining areas. The location is suitable for a dwarven, gnome, or drow settlement. Or other similar inhabitants of the Underdark with organized societies. The illustration is lightly inspired in Gauntlgrym, a dwarven city in the Forgotten Realms setting.
Most of my releases come in PDF format like you see above. The exception is map often packs and one-page-dungeons.
