Backstory
Spoilers for season 3 below.

Warden Light was sent by Tyr, Ilmater, and Torm to guard the town of Ilium, and in particular to protect the Spire and the Aurora. He was told of the true purpose of the Spire, which caused him great distress. When he left for his assignment, he invited the inventor & engineer Lucas Rosemary along. He had formerly made a connection with Lucas, drawn by the earnestness of his prayers, and that draw turned to romance. However, the Rosemarys confused the elopement with abduction. Their family friend Mardis Valamin tracked the couple down. Warden Light would not allow Mardis, who seemed violent, into the tower where his ailing husband and his newborn child resided, and imprisoned him in a mirror drawing from the Spire's power.

After Lucas died, Warden Light sought the help of Lady Nim to lock away one of his memories. She believed, incorrectly, that it would be his memory of his deceased husband. In truth, Warden Light forgot the purpose of the Spire. From then on, he maintained the Spire so that his daughter, Grace Rosemary, would never be exposed to the dangers outside.
