Palenque, Angkor Wat, Petra, Machu Pichu... All these relics of times gone by make us gasp in awe and wonder. Who made them? Where are the inhabitants today? Why are they abandoned?
All these questions can fit straight into a fantasy world - and a map. So what about it? Drawing a city is one thing, but drawing its remnants is another. Me, I think it'll be hugely interesting for a challenge!
We could also twist things here and there - a depiction of the ruins at its height, a timeline, and so on. We'll have to decide if we do historical or fictional ruins, or both. Either ways, it'll be fun!
