This is a character association module. It will enable you to set relationships both superficial and far deeper between characters you have stored within Writers Vault.
An example of this would be to use Game of Thrones character Little Finger – on the face of it he would seem a good contact and even a friend to some in the story. However, (spoilers) he is about as trustworthy as a double headed snake.
Here, using this module you can record this and keep your characters closer to how you originally envisaged them.
It would also show how many steps removed from one another they are.
It stops people forgetting about that rich uncle they had. A rich uncle who could have just paid for their car to be fixed rather than turn to a life of crime as in book 2 the uncle said if you need any money for anything let him know. Or, like the great wizard Gandalf forgetting about the Eagles he knew.
