I'm painting a Stormcast army in an original color scheme, and I know so little about their organization. Do I need to invent a whole Stormhost for them, or can individual Chambers/Conclaves of a Stormhost have their own unique names, color schemes, etc.? I'm more familiar with 40K Astartes structures, or Chaos warbands. The military structure of the Stormcast sort of confuses me. I imagine Stormhosts are more like Astartes Legions, with individual Chambers varying in color schemes and character like the Astartes Chapters. Since AoS is very open to making your army your own.

I thought I saw something about a Chamber from one of the big Stormhosts that took on the symbols and colors of one of the Cities of Sigmar. I'd like to tie my Stormcast to my (hopefully) future Cities of Sigmar army, thematically and lorewise.
