Ayman Lake was a large body of water in Natalia. King Whitson Mariner and his rabbits built the settlements of Seddleton and Kingston upon its shores after they had fled from the Golden Coast.
History
The Black Star of Kingston
Fleck Blackstar and the rabbits he has under his command sail across Ayman Lake to mine coal in the future establishment of Kingston, which was at that point, nonexistent.
When they are attacked for the first time by the Birds of Prey, they start to attempt to flee back across it to the safety of Seddleton.
The Birds overtake them, however, and they are forced to fight a battle now known as the Battle of Ayman Lake. The rabbits won in the end, but at a great cost to themselves.
