The Collaborators
When the world was young, there was nothing but a blank canvas. Three entities came across this canvas and decided to create a masterpiece on this blank canvas.
The Supplies
As the Collaborators finished their masterpiece, they wanted to make sure there was some balance kept. The Line, content with keeping an eye on their own part, kept watch on their own. The Color and The Value thought differently as they felt there was more to create elsewhere and created their Supplies, entities with a share of their power made to keep close eye on their respective aspects and make sure everything was in balance.
Waterlings are pets in the Ink/Brush universe. These are all the ones Dyan owns. There's a lot cause she is a Waterling Breeder, except Suddles who acts more like her pet.
