The basis of this map was the one created by D'rek on the Malazanempire forum. I moved Assail over a little closer to the other continents (it's pretty well-known, just avoided like the plague) and added the canonical map of Jacuruku from Blood and Bone, as well as moving it to the correct position. Its size comparable to the other continents remains unclear, however.
The map needs a little work - the Geonstel Archipelago is missing, Lether is a fair bit bigger than it should be and Genabackis is a bit smaller - and even after Assail there will still be blank bits on the map (central Lether, Stratem/southern Korel and western Seven Cities all remain fairly speculative), but we're certainly getting closer to the final picture here.
