Siblings

Night Flurry and Spring Showers are the two youngest siblings of five, and in their backstory, were close friends growing up, although Spring tended to be overzealous in teasing younger Night.  His own personal fears and phobias eventually pushed Night away from the family, and he would eventually leave them behind without telling them.  This departure hit Spring especially hard, as she blamed herself for everything she had done to Night causing him to leave.
