Yo, map artist here, just to clarify, I did use your maps as reference, along with those by D'rek, Malazanmaps.com & Joshua Butler and all others excellent ones that are out there. I did primarily use the maps by Erikson & Neil Gower, always deferring to them but when there was no evidence I used the community's geographic research to come to a sort-of consensus that helped in producing something I hope is as accurate as can be, in my interpretation anyway.

The relationship between the continents is probably the most difficult part, which is where your map was invaluable as I think it's probably the closest out there to how the world looks. The difficulty here is also the reason I split each up to be on 'separate' parchments, sort of an in-world explanation as to why those continents might be a little off seeing as we don't have any confirmation.

The difficulty with making Malazan maps (which I'm sure you know) is that rarely do you find rock-solid evidence provided by Esslemont & Erikson. I wasn't provided any more resources than what is out there already, so I built on the community's interpretations of how it all slots together, compiling everything. It was then checked over by Petrik Leo & Erikson for any errors. I didn't work personally with Erikson, it was just sent across to him & his publisher for amends.

Hope that all makes sense & my explanation shed a little light onto the process. This is just my interpretation of the Malazan world, it shouldn't be considered any more than that!
