hey let's play guess the game
"What? Ah... yes, m'lady Ama. I meant no offense. Ah, <CHARNAME>, I would suggest you obey proper protocol and present your dagger before your better."
Ok, let's take definitions from the link you provided:
a. The forms of ceremony and etiquette observed by diplomats and heads of state.
b. A code of correct conduct:
safety protocols; academic protocol.
2. The first copy of a treaty or other such document before its ratification.
3. A preliminary draft or record of a transaction.
4. The plan for a course of medical treatment or for a scientific experiment.
So you just used the word
protocol in it's late 19th century definition as
forms of ceremony and etiquette. In order for your sentence to make at least some sense in a fictional DnD setting, that setting has to contain the following:
- nobility/diplomats/heads of state with lawful alignment who have traditions to govern their behaviour
- a rudimentary bureaucracy that can transform folk traditions into a codified set of rules.
So nothing impossible in a setting like Forgotten Realms. I can let this pass.
But the problem with Lae'zel, The Destroyer of Western Civilization, is that she used the word
protocol in it's 20th century definition -
safety protocols or the plan for a course of medical treatment.
This definition is directly connected to 20th century social institutions. In order for her sentence to make any sense Githyanki civilization must have the analogue of 20th century centralised healthcare system or Ministry of Defence. Enormous, centralised bureaucratic organisation that operates through vast ammounts of paperwork, that can place an order for printing of many thousands of leaflets containing protocols for various situation for it's numerous ground level personnel to obey.
Do Githyanki have something like this? I guess they can outsource their paperwork to Modrons...
Or maybe Larian's writers are just dangerhair millenials with backgdound in capeshit fanfiction.
