Sinvaders
I think, it was an initiative coming from players. Event team supported it for a while ... afaik the one organizing this are no longer around. But you can still take the initiative and make it happened again.
I think it would need to be an ET sponsored event, unless Ryzom wants to trust me with access to control the NPC's :-D
