Who eats the most fish?

The Lizardmen of the Southlands, known as the Ungexes. They along with the Dwarves were the firstborn on the planet, and while they're powerful they still live a basic lifestyle in swamps and rivers and mangrove trees.

What is the most depressing achievement that this/ these civilizations hit/receive/achieve? Did they develop nihilism yet?
[/quote]
I think killing the Prophet of the Evergod and demolishing the Old Praelian Empire by doing so despite the many warnings is likely the biggest. I will say that, while there isn't a huge amount of Nihilism, there are nihilistic groups like the Ashen Stars and the Grey Crows, both shady terrorist organizations.

Undeath. The cause?
[/quote]
Necromancy is the art of connecting a dead body with an unbound spirit. It is not physically possible to halt a spirit from passing on, but it is possible to 'bind' a spirit to a spiritless body, or call back a spirit to its own body for a small amount of time. The cause is magic from the realm of Shadows.
