The world -- all worlds -- are full of people. On the surface we have the entire state of New Mexico, which while not the most populated state in the US, has as many folks as we need. Create all the supporting characters that your story needs. That said, these characters, for the moment, must live in your imagination and in descriptive text. Until we have some additional art support, it will be problematic to place characters in the static web-world of La Casa. I am working right now to get Elpis and Imzadi in place in the story.
The problem I have encountered is that because of the static nature of the site, each person only gets to be in one place at a time. This is much more constricting than the free movement we enjoyed in MOUL. For La Casa, I have given each character a place to be:
Jim Nakai is just beyond the Zandi gate.
Marie Nez is at her hogan.
Dr. J. Timothy is walking outside at UNM.
Sophrosyne is standing by the stream.
Okaasan is in the foyer.
When the scenery is developed
Elpis will be in the office and
Imzadi in the kitchen. We need some help on the art in order to place each character in situ.
Thorne may be well placed out back in the kitchen garden or tending the fire outside of the sweatlodge.
Not all our characters have to take rooms at La Casa. Some may live in the area -- on land of their own purchase or inheritance, or in private detached hogans built on La Casa land. I have already allotted rooms to the present characters -- KoHama, Okaasan, Elpis, Sophrosyne and Imzadi -- and I can lock off a room for Kelsey if you want.
On new ages: since we have proposed that the ladies at La Casa were amongst the first to enter the Cavern along with the gents from Cyan's storyline, then there is no reason to think that we did not nick off with several linking books. We would guard these books zealously, and never speak of them with "outsiders." Keep in mind that not only would we be concerned with a legal move by DRC to seize those books, but also the US Federal Laws (1906, 1979, 1990) that govern the recovery of artifacts. The books form the core mystery for our visitors to solve.
For right now, folks can suspect we have books all they like -- we ain't sayin' nothin' 'bout no books, no how.
Keep those creative juices flowing and let the story evolve.
