Lahn is a scrivener of the ancient scriptorium that records the history of the world.
Her family has been observing and recording the world since its beginning. They write in an ancient language whose letters channel powerful waves generated by the world's memory itself. As the latest of her bloodline, Lahn masterfully wields the letters both as a talented historian and as a powerful protector of the scriptorium.
She uses archaic dialects and often talks as if she is writing poetry. Because people often misinterpret the trait as being smug, she secretly practices talking normally but has hard time grasping the concept of urban slangs.
She recently discovered her letters emanating unusually powerful waves. Sensing something drastic is occuring in the world, she ventured out of the scriptorium to witness the event with her own eyes.
