I've always been a big proponent of making it more of a cinematic universe type feel. But not on the silver screen. more of a netflix/HBO type thing: Season 1: Heart of the Garden Movie 1: original VoG (Osiris's team) Season 2: VoG/Crota's End Movie 2 (comes out mid second season): Crota's orginal raid team with toland & Eris Season 3&4: Taken War (features some old school fundament flashbacks) Season 5: Rise of Iron Season 6: Age of Triumph & Ghaul (intro of Calus/shows flashes of Prince uldren's kell ascension) Movie 3: Return of Osiris Movie 4: Intro of Xol/Nokris season 7: Forsaken/Whirlwind explanation/alliance with fallen (hinted in previous seaons) Movie 5: Drifter's intro Season 8: Penumbra/usher in of darkness/realization of Sa'vathun and Xivu Arath Season 9: Continued battle with Sa'vathun & Xivu Arath; Calus shadows; Quira Betrayal Season 10: final fight with Darkness/Savathun/Xivu Arath; rise of a Kell; Calus's intentions revealed; Vex cliffhanger thing Now those aren't clear cut. you could intertwine the darkness in a lot of seasons. forshadow the hive sister, forshadow calus and many other things. Just though all of that would be a cool idea.
