On the note of pronouns/language since you bring up the canon language perhaps only having 'they', I spent a while working on a more gender inclusive language a while back and came up with a neat idea. Read if you wanna (its long, sorry).

The basic idea takes the concept of keigo - literally translated to respectful language, it's the Japanese grammatical structure for adding respect/formality. The language would have several different levels of formality, for the purposes of pronouns we only really need 2 however so I'll only go into the 2 we need.

• First, the "standard" formality. This is the formality you would use with strangers, coworkers, bosses, etc. In a more fleshed out language there might be more formalities above this, but they all would treat pronouns essentially the same as the standard. All pronouns in the standard formality are agender. The closest English translation would probably be they/them although that doesn't convey the true absence of gender that standard formality has. It is simply nongendered.
• Second, we have the "familiar" formality. This is the formality you would use for close friends, family, etc. In this formality you do have a number of explicitly gendered pronouns, ranging from the standard masculine/feminine, to various neutral/nongendered pronouns, to even perhaps a number of different "gradient" pronouns for different mixes of gender identity. And finally of course someone can always choose to retain the truly genderless pronouns of standard formality should they prefer a more truly "agender" option.

The idea is that when speaking to strangers - and in situations where you need to be respectful and formal - gender is entirely absent. Thus there is not really a risk of misgendering a stranger without learning their preferred pronouns. Then when two people become close enough, they will switch to their familiar pronouns and thus affirm each other through their language as a sign of their closeness. 

Since exchanging familiar pronouns is baked into the structure of the language, it becomes a natural part of introducing oneself. An English approximate would be like introducing yourself as "X, familiarly Y - xe/xer" or even simplified to "X, Y - xe" where X is one's family name/formal name/title and Y is one's personal name. For my MC it would be like introducing her as "The Eye, Lyria - she". It also implies some rude, culturally significant ways to introduce oneself like only introducing their formal title without their familiar pronouns and name thus implying that they do not intend to let you get close to them.

This makes a language that makes no default assumptions about a stranger's gender, but still retains gender expression and affirmation through language. Furthermore I think it canonizes gender affirmation as something more intimate and friendly, a sign of respect and friendship.

Sorry if that was a bit long and rambly but I am a language nerd, couldn't pass up the opportunity to talk about pronouns and gender inclusivity in fictional languages. Hope it was an interesting read at least.
