Monsters of Discordia
Odessa was home to all kinds of monsters, stretching back beyond recorded history. Now that the Concord has fallen, they are flourishing again, and many new things have crawled forth from the ruins of that empire.
Deities
Some beings on Odessa are so powerful that they defy human comprehension. They are very difficult or impossible to kill, mortals are often beyond their notice, and the people of the continent usually have worshipped them at one point or another.
The Transformed
The Transformed are a collection of creatures that were something else before the Concord fell. Whatever happened that brought them down and ushered in the world of Discordia shifted reality itself. Some changed instantly, while others were exposed to eldritch and abyssal energies more recently.
The Plagued
A few short years before the Fall of the Concord, an alien force invaded Odessa from the skies, bringing with them a plague that nearly ended the war between the Conks and the Rebels overnight. Now, few of these creatures remain, but certain hotspots are scattered around the continent, and every illness is viewed by the survivors as something to fear.
