Megadungeon: Oldcity Sewers Encounter Table (d30)

The first of six encounter tables for the Foabeléth Ordirrex, the megadungeon beneath Booezor.  But first a small overview.

Minor Dungeons: The Foabeléth Ordirrex is comprised of many smaller minor dungeons, six of which connect to the surface. Booezor is built on older layers of its previous iterations, particularly the Ezordirrexian era when the city-state as one worked for the glory of the Autarch, and the elder magic era, when the Sculpted Mountain and the first city was built.

Oldcity Sewer System – the functional and nonfunctional sewer systems of several iterations of the city built on top of each other. A huge mess of tunnels and chutes that spans more than twice the length of the city.

Tomb of Mountain's Heart – its earliest parts were dug deep into the heart of the Sculpted Mountain, and the subsequent generational levels were stacked on top of each other one after another as the city grew. It occupies little horizontal space but a great deal of vertical space.

Filth Pits (Refuse Dump) – the size of small town and with a population of people to match, the city's dumping grounds have become their own multi-leveled ecosystem and cave complex, eventually meeting the sewers or the twin underground helical rivers.

Labrynthyne – a quasi-extradimensional prison structure built to contain magic users. It is filled with creatures that ignore, twist, or feed on magic energies, convicts to dangerous (or hated) to kill, and beings from other planes.

Moonmetal Mine – silver IS magic in the “Furthest Lands”, not a currency. Occasionally silver or Moonmetal will rain down from the sky as meteorites. The most closely guarded mine on the lower slopes of Booezor's Sculpted Mountain was once a steady source of the magical metal.

Giant Termite Mound – a great nest of giant termites at the base of the sculpted mountain is believed to connect to the deeper parts of the megadungeon.
