SearchStoryteller
This term is used for a staff member who's primary concern is to support and run player driven plotlines and to help the game world feel more realistic. Storytellers can, and will, be found anywhere in the game, from animating the sand hitting your face, or an NPC attacking you, to supplying Great Merchant Houses with items for sale and driving plotlines.
If anything in the game begins to react to you in a way you are not used to, most likely a Storyteller is involved in some fashion, whether it be coding the reacting thing to respond in such a manner, or taking a direct hand via animation. Most Houses and Tribes in Armageddon have two or more sponsoring Storytellers who are responsible as well for answering email in a timely fashion, and providing assistance for events planned or questions asked by the playerbase.
