Numerology in your conlang

Many IRL cultures have numbers which are considered special or lucky. For example, seven is considered lucky in Western culture due to its association with completeness, while eight is considered lucky in Chinese culture due to its association with wealth. In Ancient Selemian culture, that number is:

2763

or in Old Selemian:

Jičič mējas kaja rurik qalame mâlu

[ˈjɪtʃɪtʃ ˈmeːjɑs ˈkɑjɑ ˈɻʊɻɪk ˈqɑlɑˌmɛ ˈmalʊ]

Lit. two thousand seven hundred sixty three (the -e suffix in "qalame" functions similarly to the -ty suffix in English)

So, you may be asking: why 2763? Well, according to the Ancient Selemian creation story, man was created (or rather descended) 2763 years after the creation of the world. Many (though not all) use this 2763-year period as the basis for their calendar system, dividing it into four eras:

• Era 1 - the first 2763 years from creation to man

• Era 2 - the next 2763 years from man to the founding of the Old Selemian Kingdom

• Era 3 - the next 2763 years from the Old Selemian Kingdom to the founding of the New Selemian Kingdom

• Era 4 - the last 2763 years from the New Selemian Kingdom until today

You may still be asking: why specifically 2763? No one definitively knows, but somehow it stuck, and even long after the decline of Ancient Selemian culture, this is remembered as one of their most distinctive aspects.
