The planet Wayland was conquered by a Dark Jedi, specifically Joruus C'baoth, who was an insane clone of the Jedi Master Jorus C'baoth. He compelled the indigenous Myneyrsh, Psadan, and Human inhabitants to coexist, thereby establishing his personal kingdom within the city situated at the foot of Mount Tantiss. Mammon Hoole, the Shi'ido anthropologist, made reference to this conquest in The Essential Guide to Alien Species, during the era of the New Republic, when writing about the Myneyrshi and Psadans.
