Re: OOC
RN I am good with keeping it as is. Having the posts in a big block keeps the posting consistent so for example, Eno's conversation with Amleth doesn't zoom ahead faster than Neva and Hale's storytelling. Also, too many separate NPCs might increase the amount they talk to each other which can end up making a game more about the NPCs than the PCs (I'm not too concerned about that for this particular game though).
Another option could be create one for each major NPC character for when they are the primary actor in a scene. So if we are exclusively dealing with Nezaria, then posts come from her, including minor characters & GM moving things along. The center of attention could shift in the scenes and the character could change. I haven't seen a lot of games do this... maybe it ends up being confusing?
The only easy change that may be an improvement I could think of is: when the action is split (like it is now) add a bit of a header indicating which characters are the primary actors in the scene (incl. NPCs and potentially PCs).
Like right now its,
"Amleth, Eno"
"Audience, Neva, Hale"
"Nezeria, Alice, Masked"
I didn't forget about Eve. But unsure where to place her; she seems more interested in Eno and Amleth at the moment, but could also join with Neva and Hale.
Long story short. I do not have much preference and spent way too much time typing :D
