A few characters and their pronouns! Trans and nonbinary characters of Blue Horizon.
Soyeon:
A main character I was thinking about discussing at one point was Soyeon. In the epic science fantasy book 1, Soyeon and a Mystery Character having a small storyline about using they/them pronouns. Soyeon utilizes she/her pronouns too--at first I was stressing about how to note it, but figured out eventually that a quick mention wasn't difficult at all.
(My old Tumblr notes on January 22, 2023: In the WIP as it is right now, I haven't been able to figure out how to work it in, but despite Soyeon and a Mystery Character having a small storyline about using they/them pronouns, I originally wanted Soyeon to have a further conversation about utilizing she/they. Have to figure out whether I can bring it up in the first book or not later.)
Posh Hat:
utilizes they/them.
Armando Rivera:
Blue Horizon is 2000's (and earlier) zeitgeist, so Armando will not be shown to utilize these pronouns for a long time--however, Armando's pronouns are he/she/they!
Mario:
Mario is a trans boy (+ trans man later in the timeline)! He uses he/him.
Rajani Chandrani:
Rajani is a trans woman! She uses she/her.
Layla Chandrani:
Layla is nonbinary and uses she/her and they/them. Pretty sure she was one of the "mystery characters" listed above back when I was assuming I wouldn't talk about the Part 2 cast at all.
As noted above, there is a further mystery character shown to eventually change how they utilize pronouns. There's one who I'm hoping comes off questioning it at one point, as I have a lot of thoughts about certain characters and English-style pronouns!
Those are the main characters of Blue Horizon epic science fantasy book 1 who are openly trans, openly nonbinary, openly ponder or openly use pronouns that aren't cisnormative. (Armando will be so later in canon.)
(So far.)
An interesting side note: in Bangla we don't have gendered pronouns!
The people in Blue Horizon speak different languages that coincide vaguely with our languages (but also know of and even utilize languages like Bangla, Spanish, English, etc. due their interest in ancient Earth).
So the pronouns listed coincide mainly with English and languages that have he/she/they.
