Sorry for disturbing the development, I'm a translator of this mod.

This is actually NOT an issue, I'm just struggling about the answer.

As the title say, I found that there is a trait call "Sirben" now inside the en_us.lang file, but I have search all over the internet and can't even find a definition of the word Sirben, so I came here, wondering if I can get a answer from the contributors.

A link to a Wikipedia Page will be the best answer, or you can just type some explanation of the trait, that will be OK, too.

Sirben is the name of one of our Discord members :) Keep it untranslated. It is an easteregg, but I wasn't aware of the massive confusion it would cause hehe

I see. Well, I will still translate the rest of the words in the sentence, and maybe add a bit of sarcastic intonation in it.

Hopefully the translation can match the meaning you want.
