Explain what specifically?

In 2015, there was a writing event on the forums held by the Global Moderators. (Moderators for the game itself. Not the Wiki.)

Users submitted stories for roles. The stories that were rated highest were placed as the official stories on the Wiki.

New roles came out recently, so there will likely be another contest. The moderators are discussing how to go about it.
