Wings Canon is the "true story" of Wings, and is used to determine a cohesive continuity.
There are two levels of Wings Canon: T-Canon and P-Canon.
T-Canon comes straight from the author, Lord Of The Marsh, and is the decisive ruling in the "Wingsiverse".
P-Canon comes from anybody else, and is continuity so long as it does not contradict T-canon.
In the case of a dispute between the two levels, T-Canon wins. In the case of a dispute within levels, the older one wins. P-Canon can be promoted to T-Canon in several ways:
1. A P-Canon element becomes T-canon if referenced in a T-canon context.
2. A P-Canon work becomes T-canon if declared so here.
