What's happening in your world?

['thul]

It is the user account name 'thul use on that RP site, so yes, its related to those role playing games...

as for what it is, that is a bit vague...

the ground is sandy, the mountains behind stone (obviously) and the structures are of some sort of crystal. 'thul used a Sapphire texture to render it.
the tallest structure is about 150m tall, with varying heights on the others. these beings have not quite decided what sort of buildings they are, hence the vagueness.

The image itself is not really related to any one RP. It could be interpreted to be related to many, but the relation would be coincidental.
