Barsoomians are humans who'd escaped from the end of Mars.
The Barsoomians, who first came to Eris from Mars, are referenced in old lore as the Firstmen. They came to Eris long ago and have since commingled with elves, Earthmen, and perhaps other races. The purest descendants of their line dwell today in the Stygian capital of Amon Sin. (See also, STYGIA, for description of the native folk purporting Barsoomian ancestry.) Others of their old numbers have been absorbed by northern barbarian tribes. A remnant of the Dearg (Barsoomian half-elves) dwell in the Wild Lands of Oros, especially near the desert known as the Sands of Nod. While the Barsoomian of old is sometimes described as a giant, no modern evidence of this exists.
