NCF – Extended list of Neutral creatures.

By the way, I once created a creature called the King of Wyverns. It had the ability to consume corpses. Because of this, the game would crash at the beginning of each turn. The reason was simple: I had assigned this ability to the King in the spells, but I didn't specify it among the creature's abilities, and the game couldn't determine it. I added it to both the spells and the abilities, and the crashes stopped.
