The Wonders of your world

[Ahnehnois]

In a great lake in the middle of a desert, I have a city (Goran'ixe) made entirely of crystal, which lies beneath a massive crystalline dome.

I also have a hundred mile indestructible stone bridge across a strait that was built by demons.

An unearthly sized massive volcano where dragons congregate.

A Great Barrier Reef-esque reef with underwater civilizations.

A massive dead lake with a well to the Negative Energy Plane and a canal several hundred miles long built to relieve the vile magical forces that accumulate there (unsuccessfully).

Lots of stuff, really. Maybe I'm better at worldbuilding than I thought I was.

Some of mine can be found here, and here on my homebrew world wiki.

A few of my more favorites are the

- Answan Suwat, a massive "dam" hundreds of miles long, designed to control shipping and lead great armies on a conquest to the northern part of the continent.
- The Blue Desert, a magically cursed desert of azure blue sands that is deadly poison to anyone coming in contact with the sand
- Battlegroup Redblade, The Bloodtide and the Northstar - technological battleships (with the bloodtide being a submarine) of an age gone by that haunt the seas. The battlegroup's sole purpose is to scour the seas for the shanghied crew of the bloodtide, while the Northstar is a broken hulk half-sunk in a swamp and transformed into a fortress-city.
- and finally, JroJro Castle - also known as the Astral Castle, whose location changes each full moon. From it depths rises an army hell-bent on conquering the local countryside, but by the next moon it is cursed to move on and seek to create a new dominion elsewhere on the continent.
