Most of the screenshots are from missions that take place in "Azerothformed" territories that the Enclave converted to be habitable for humans, elves, dwarves and gnomes. In time we will provide more detailed lore sheets with worldmap and all the juicy stuff. The sequel is gonna be a soft-launch into the new world, interlacing rather mudane feelings with the otherwordly.
Because Jiluun is original plot, we have all the artistic liberties at creating it. Unlike Outland, I design it with as much consistency with rules of physics, basic principles of biology etc as I can and I definitely want it to be believable. It doesn't mean that I don't want it to be appropiately crazy and strange :]. Still, completely fantasy places like Outland have no basis to host water sources, atmosphere or even gravity. I can say that Outland feels more "fairytale" then "fantasy" for me, while me and Macielos represent the school of worldbuilders that care about world consistency. Fantasy writers want things to be "too cool" sometimes.
While I'm the crazy guy who likes creating strange stuff, Macielos is working on social, political, economical and cultural layers of the Enclave. He does what he's best at - a civilization. Enclave has specified culture, social paradigms, administration, military doctrine, theme... Enclave is a fully-fledged pocket civilization, with all strong points and flaws of civilization. I can say that the Enclave hosts multiple parties and is a dynamic political arena to compete for different sources of influence of varied agendas and aspirations, but still they cooperate to keep structural integrity of the Enclave and ensure it's survival.
