Logres is the sixth sim of the Adam ondi Ahman continent, and the third sim of the Demesne of Lyonesse. It was delivered to Tascha Klees on 24 August 2007, and is immediately north of Pendragon and northeast of Deseret. On 6 September 2007, the entire sim collapsed into the sea, requiring a complete terraform.
Logres and Splendour Lyonesse now form a single landmass, with a significant amount of sea between western Logres and the two islands of Pendragon. A ferry connecting the four Demesne of Lyonesse sims is in development, and will put in at the extensive docks of western Logres.
