Reiner I (Lukas son of Arnould) was crowned the first ruler of the Kingdom of Dakar when they pacified much of the Zun River valley. He spent very little time at Celinus while it was being built, preferring to leave the administrative work to his brother Erart and daughter Hermineite. Instead he spent most of his rule in the field, along with his sons, conquering his neighboring tribes. When he died in the field his sons returned to Celinus with his body for the first royal funeral.
His reign as king was short-lived, but he was already well into his years when he was crowned so it was not unexpected. His reign was dominated by conquests as the Dakarians kept several large warbands in the field at all times.
