Old Lek’re is a dead language; it was the primary language during the time of the Old Lek’re Empire, but has since fallen out of use.
It is believed that Shuka is based somewhat off this language. Some Lek’re still speak this language, at least in part. (Usually, they can say hello, good bye, and your mother humps sewer rats, and that’s about it.) A handful of scholars can read the language, but the pronunciation of many words is uncertain.
