Thanks Harrg, yes I must admit I love tectonics! Regarding Osmor, I was initially wanting a 'Sakhalin' style island then before I knew it I had Kamchatka as well! Other shapes I borrowed are Baffin Island (the main landmass in Fjordhaerne) and Sognefjord (Norway), the main gulf on the west coast of Skardhyr.

Skardhyr was meant to be heading towards Qaruma and Osmor rifting from it, but looks like I need to rework that. So regarding the coastlines, is there any in particular or do you mean all of them in general?
