Qophper has its own writing system and numeral system, used in all kingdoms present

The Qophper Alphabet is based on the Hangul, the Korean Alphabet, having 27 consonants, 21 vowels and 5 coda accents

The Qophper Language (Qophpirian) is a mix between English, Greek and Korean, and in the case of names, like name of a place or name of a person, they are written the same way they are pronounced, for example: the name "Ferrer" in Qophpirian would be written "Færəl"

1 hour = 48 minutes

1 day = 37 hours

1 week = 5 days (3 workdays and a weekend of 2 days)

1 month = 25 days

1 year = 15 months
