Forces of Cularin Episode IV: Force Convergence

From the introduction:

This interactive is based off of events occurring in the finale of Forces of Cularin Trilogy that premiered at [Winter Fantasy]. If you have not played the trilogy, then be warned – something that surprised many people will be completely spoiled for you if you elect to participate in the interactive. The event, while not central to the modules, is key to Living Force, and if you want to avoid spoiling the surprise, we strongly recommend you wait outside during the opening moments. Even that isn’t a guarantee, though, since the point of the interactive is to interact, to be part of the story.
