The Xiavos are an underwater race said to be descended from the Hurdin. They have built large underwater empires but have had a general isolationist policy to what they call the surface world. They can often raid the surface without warning and even attack ships, though only doing so to targets that are unable to defend itself. The Xiavos are intelligent and proud but also a highly ruthless race and practise slavery. Xiavos are humanoid with long lakes that when placed together resemble fish tails, and tend to have scaly skin and thicker bodies. Xiavos are heavier than surface humans of similar height, with dense bones, thick torsos, and strong swimming muscles, though their bodies are naturally buoyant enough that they move with ease underwater. They can breathe underwater. Their capital city is the undercity of Seranthi, and their Empire the Xiavos. The inhabit the oceans and sea and have occasionally made trade, though preferring to remain isolated Xiavos for Allurian history have guarded ancient sites and fallen temples as well as elemental portals for these have presented the greatest threat to their survival. They have wars against various sea monster, elements and aboleths and various Kuo-Toa tribes
