So, after the latest 3.7 story, we have a bit of a situation with the form tag names for Cyrene (Honkai: Star Rail).
While "Ripples of Past Reverie" was the title in the drip marketing for the playable Cyrene form we currently tag as Cyrene (Ripples Of Past Reverie) (Honkai: Star Rail), in the latest patch this name is used explicitly for the other form of Cyrene - Cyrene (Aedes Elysiae) (Honkai: Star Rail) - including in the name of the BP icon for her - https://honkai-star-rail.fandom.com/wiki/Ripples_of_Past_Reverie:_Keeping_Promise_(Profile_Picture).
Now, I think the tag name qualifier "Aedes Elysiae" is probably fine - "Daughter of Aedes Elysiae" is one of the other names the game uses for that form, but "Ripples of Past Reverie" is now pretty confusing since our usage is opposite of the game's usage, and unfortunately there's not an obvious replacement that I know of. So I'm going to toss out a bunch of options for discussion:
Ripples of Past Reverie
Keeping the status quo and not changing anything
Pro: This is the tag name we're used to
Con: Ambiguous and opposite how the name is used in-game
No Tag
We could not tag this form and treat it as the "default" form/costume which is just tagged as Cyrene (Honkai: Star Rail).
Pro: Avoids the issue, simplifies the tag hierarchy for alternate costumes like Cyrene (Nylon Japan) (Honkai: Star Rail)
Con: The playable form is less than half of Cyrene (Honkai: Star Rail), which is usually the point where tagging the default costume/form becomes useful
Ripples Rejoined
This is the name of the event warp for the playable character
Pros: Similar to "Ripples of Past Reverie"; is an unambiguous phrase used in game (but not in story)
Cons: No one actually uses this name; not sure how recognizable it would be
Demiurge
This is a title that is used in story for this form.
Pros: Short; used in story
Cons: Actually a bit of spoiler that this form is the Demiurge, though that may be less important over time
Playable
Pros: This is one of the ways people actually refer to the form
Cons: A bit awkward for implying non-playable alternate costumes
Big
Pros: This is the other primary way I've seen people actually call the form
Cons: Just seems like a weird tag qualifier to me, though I guess it isn't that different than "young".
Regardless of what we pick as the actual tag we may want to consider having cyrene_(playable)_(honkai:_star_rail) and cyrene_(npc)_(honkai:_star_rail) aliases to help discoverability. (And/or cyrene_(big)_(honkai:_star_rail) / cyrene_(small)_(honkai:_star_rail) )
Also regardless of what we pick, there's a question of whether to keep Cyrene (Ripples Of Past Reverie) (Honkai: Star Rail) as an alias to the new name (despite the game's usage), reassigning it as an alias to Cyrene (Aedes Elysiae) (Honkai: Star Rail), or getting rid of it entirely.
Also also kind of related, should Mem (Honkai: Star Rail) imply Cyrene (Honkai: Star Rail)? Mem is another form of Cyrene, though it's visually more distinct and also a spoiler. The precedent of Sam (Honkai: Star Rail) would cut against the implication, but tags like Robin (Robird) (Honkai: Star Rail) and the like are a precedent for one. My inclination is to not imply; but I think it is worth discussing.
