The Sea of Fire

This is a seemingly endless ocean of magma, larger than any single sea in Eberron. Ultimately, the Sea of Fire wraps around on itself; head north from High Hearth and you’ll eventually find it again, but it may take a month of travel. There are islands in the sea, spires and mesas of basalt and obsidian—some are inhabited, but many are barren and empty.   Salamanders sail the blazing sea in ships forged from blackened steel, and azers fly over it in balloons woven from brass. Many of the islands hold teleportation circles traced in continual flame, with a word inscribed in Ignan indicating the destination. Any spellcaster with proficiency in Arcana can expend a spell slot of 3rd level or higher to activate a portal—though unless they speak Ignan, they won’t know where it leads. Here are a few noteworthy destinations.
