Centuries before the events of Ori & The Blind Forest, before the days of ascension to Nibel's Spirit Tree, Sein was an adventurous lady traveling the world and going on a great journey!

She fought many foes, rescued people, and was all around a very nice person. She also got into a fair bit of embarrassing and awkward situations over the years. Among them was when Sein decided that instead of going naked all the time like most spirits, she would try out a set of strange clothing articles created from a memory of an ancient spirit. She think she looked so good in them! Gesseritch, future Spirit Tree of the particular land she was adventuring in (and one of her many, many lovers over the years), agreed too and immortalized the moment as a Light memory image.

Centuries later, Gesseritch is fond of embarrassing Sein and generally make her swear aloud by broadcasting to every Spirit Tree he knows this image.

"I hope a gust of wind knocks you into a woodchipper, Gesseritch!"
