Just playing right now, using the techniques I learned in this month's challenge and the Veil Vale experiment.
I'm working on one of the many sunken city-states of the Fallen Lands, the campaign world I'm developing on Eruvian.com
You'll noticed I robbed the content from my challenge, though I may actually create new structures (haven't decided yet, as these structures are appropriate)
This is an ancient greco culture, and Ketia was the first city, founder of the civilization and greatest capital in the known world until it fell into the sea, 40 years ago during the cataclysm.
Anyway - playing with some underwater plants and plant-like sealife. I used 3D to generate that fractal sea bottom. I'm just starting out - any suggestions?
I really want to do some relief map structures in a regional sea bottom map, as well. This is the first of several sunken city-states I need to develope.
