As a heads up, due to the nature of the first part of the RP (Being, well, a desert, with few [i]immediate[/i] hazards outside of dehydration) There's going to be several long timeskips. Always keep in mind how your characters might be growing/interacting with each other over these long periods. Once (If we don't die horribly somehow) we reach the end of the desert, things will turn to a more "normal" RP pace for awhile. So, different dynamics than you all may be used to.

I suppose a way to say this is most RPs are "front heavy" where most of the important character interaction takes place over a relatively short timespan in the story (Getting to know each other, establishing ships, showing the nuances of their personality and history) whereas this is going to be more spread out. Say, A and B hung out and flirted during the first few pages of the RP, but over timeskip 1 A and C noticed they both have shared interests and spent most of their downtime training together. Etc.
