After the battles of Albion, the Slaan, or maybe Slann, I forget which, altered the climate of Albion. The centre, so far, is the only bit affected, and is now like a jungle. The plants of Lustria have been taken over as well. A new temple city is being built, under the rule of a fourth generation Slaan, if my memory serves correctly. Basically, as Albion is where the Old Ones lived, and is a focus of so much 'anti-chaos power', for want of a better term, the Lizards decided they should protect it. As a result they're slowly but surely turning it into a tropical paradise, and are driving out the local humans and giants. Considering just how far north it is (comparable climate to real world Scotland, near enough), warming this place up is quite an achievement.
