Sister Temarin, or as her wards call her Sis Tem, wanted nothing more from life but to take her vows and care for her little ones. The sisters of the Verdant Glenn Orphanage had raised her from a toddler. Tem owed the temple her debt, and wished to spend her days repaying it, doing what she loved.

Then the ground parted, spilling monsters on to the Earth and mysterious portal creatures spirited her children away. The apocalypse shattered the world and rebuilt it in the invading scourge's image. Fortunately for the world's residents, the gods didn't abandon them. They sacrificed their divinity, creating the system, granting the people classes, skills, and spells that their paltry magic could never achieve.

Now, Tem must hunt down her missing wards with nothing but her habit and a staff. Each child she saves grants her strength, but the horrors and new pleasures of the changing world leaves her questioning her faith.
