Fernia, the Sea of Fire is a continually burning landscape. Plates of compressed ash and debris float atop oceans of liquid flame as mountains ooze with molten lava.[1]


The plane of Fernia is comprised almost entirely of liquid flame. Fire constantly rages, without the need for air, and what little air exists ripples with the heat of continual firestorms.[1] A large landmass of ash is said to sit at the center of Fernia. On it is the mythical City of Brass, where the efreeti call home.[2]

Fernia manifest zones in Xen'drik result in the growth of Fernian Firepeppers, a pepper coveted by chefs across Khorvaire.[3]


Manifest ZonesEdit

Effects on the Material PlaneEdit


When coterminous, Fernia generates intense heat on Eberron, especially surrounding volcanoes. Air temperatures can reach as high as 140°F, causing pain when breathed in. Existing lava or magma pools become hotter, dealing more damage. At areas of high heat (like volcanoes or lava pools), inhabitants of Fernia can cross over into Eberron. In these areas, fire spells become more powerful.

Fernia becomes coterminous for one month (the midsummer month of Lharvion) every five years.


When remote, areas of great heat on Eberron (volcanoes, lava pools) become more intense. Outside of those areas, casting fire spells become more difficult.

Fernia becomes remote for one month (the midwinter month of Zarantyr) every five years.


  • Years ago, when Fernia was coterminous, an efreeti named Ayim led a group of ember guards across the planes to Eberron. They tried to carve out a new kingdom in northern Xen'drik, but were defeated by the drow.[8]
  • The plane of Fernia is coterminous during the adventure Pit of the Fire Lord, causing the temperatures in Sharn to get up to 105°F.[9]
