I have an idea to flesh out the nature of his relation to the Vex, Kabr, Saint-14, the VoG and what caused him to be officially exiled. I also have a few more in the pipeline that detail Red Death's inception, first contact with Crota and a Raid party that (re)(un)ended Atheon [spoiler]#paradox[/spoiler]and it's implications for the City. I'm trying to keep them small and contained stories so I don't lose narrative steam in complexity. But they might end up being pieces of a bigger picture story later on.
