The Codex is a conglomeration of all that we know about the canon GGO universe and all that we as creative types can add to the world.

One
When submitting a piece for review please put it in the "Awaiting Approval" section so that the mods will know that the WIP is finally done.

Two
Just because you submit something it doesn't mean that it will be accepted. The item has to be looked at and the idea may need time to settle before a decision is made.

Three
Even if you create an entry in the codex (I.E. a weapon) it is NOT a reason you DESERVE said weapon, it is an influencing factor in if you're more likely to get it however.

Four
Those who do create the item will have their name posted in the entry to give them credit for the work that they put into the entry.
