Maps

There is another thread in a similar vein, but I'll repeat the answer anyway.

Most areas are random, to a greater or lesser extent. We can place a special non-random boss room inside an otherwise random level, for example.
Towns not are random so far.

I am unfamiliar with Ragnarok Online in particular, but...
Wraeclast is a desolate, unforgiving place that actively seeks to destroy and consume all that dare tread its fell shores, especially those few remaining souls retaining any semblance of vitality.
So there aren't exactly tourist-towns sprinkled across it.
