Orodruin

The Volcanic Island of Orodruin
Orodruin (Elvish for 'Fire-Mountain'), named for its active volcanos, is a tropical island far to the North of the Sea of Baaj and the main islands in the archipelago. It lies to the East of Highwind Sea and prominently features dense primordial forests and scorched, barren lands surrounding the island's many volcanoes.

Many strange flora and fauna are exclusive to Orodruin's hostile environment. It is said when the island's volcanoes erupt, a gate to fiery Phylegethos (the fourth layer of the Nine Hells) is torn open, allowing all manner of horrors loose over the island.

Zur and Zura
Across the Channel of Fire, a treacherous body of water directly south of Orodruin, two expansive and polymorphic natural salt-pan islands lie, shining white under the sun. Zur and Zura are both are perilous to ships and are generally avoided due to their ever-shifting, unpredictable salt-sands. Legends tell of a mythical library thought to be buried and forgotten under the sands of Zur or Zura.
