}}Mar'saval is one of three great ruins from the Âge des Démons in the jungles of Q'Barra. Sunk beneath the Basura Swamp, Mar'saval has become a holy site to many Homme-Lézard tribes.

Ten million years ago, Eberron entered the Âge des Démons; a world where the powerful evil fiends, known as the Maîtres Démoniaques ruled. Khorvaire was controlled by these fiends, with their followers, the Démons, Rakshasas, and Sorcières. However, the Dragons of Argonnessen and the Couatls of Xen'Drik joined forces, and purged the world of the Maîtres Démoniaques. Their citadels fell, some abandoned, and some with the fiends trapped within.

In the land now known as Q'Barra, three major citadels of the fiends fell: Ka'rhashan, emptied of evil and now the home of the Draconien; Haka'torvhak, home to the trapped fiend Masvirik and the corrupted dragon Rhashaak; and Mar'saval.

Once a great temple of brass and granite, Mar'saval sunk beneath the Basura Swamp. Powerful enchantments prevented the water and silt from seeping into the citadel. Local Homme-Lézard tribes often leave tributes to their Draconique gods at the sunken minarets of Mar'saval.

There is one entrance to Mar'saval above water, and some say that one clan of Homme-Lézard has taken to live within Mar'saval: the Effondré Bones clan; however, rumors say that this clan has been corrupted by Mar'saval, and have devolved into feeble creatures. They say that the Effondré Bones clan have allied with Troglodytes living within the ruins.
