Serpent's Skull in Eberron
Xen’Drik is the continent to the south of Khorvaire, a jungle continent of vast size and varying climate. Xen’drik’s coastline has been mapped, but its interior remains largely unexplored, and the continent has a reputation as a land of secrets, danger, and mystery. Xen’drik and Khorvaire are separated by Shargon’s Teeth and the Thunder Sea.
Sahuagin tribes guard the seas between Khorvaire and Xen’drik. Some tribes attack any who attempt to reach Xen’drik; others work as guides, often trading, assisting, and negotiating deals with explorers and merchants.
Xen’drik was once home to a civilization of giants, with whom the dragons risked sharing ancient magical secrets. This civilization fell into ruin due to a Quori invasion, an elven rebellion and then a war against the dragons of Argonnessen some forty thousand years ago. Primitive remnants of the giant civilization still exist within the land’s jungles and mountains. Tribes of drow, those remaining from the enslaved elves of yore, who worship the scorpion god Vulkoor also live among the ruins of the giant civilization, possessing the most advanced society on Xen’drik. The elves of Aerenal, once ruled by the ancient giants, originate from Xen’drik.
Currently the only outpost to the vastness of Xen’Drik is the Settlement of Stormreach on Skyfall Peninsula.
