A King of D'ni.
During his reign groups who strongly disagreed with the theologies of his grandfather Veesha, sought to make their own causes more widely known. The most dangerous of those groups was knows as the Judges of Yahvo. It was in 1303 when a writer mysteriously left the Guild of Writers and Books and Ink went missing from the respective Guilds. Koreen ordered tightened security on the Guilds, as well as a massive search for the vanished Writer, but all to no avail.
It was in 1323, with his wife about to give birth to his first son, that Koreen's palace was attacked by a group of Judges, along with Pento warriors. Koreen ordered his family out of the palace, as it was quickly being overtaken, and together they traveled to the other side of the city where a special Linking Book to a secret Private Age was waiting for them.
Koreen continued to live in the D'ni City during the Pento War. The Judges began to destroy more of the city and kill more of its citizens. Koreen poured money into the City Guard as well as the small military of the day, although it seemed too late.
In 1352, Koreen was assassinated by a group of Pento warriors being led by Judges. The city was thrown into complete chaos.
