Have you heard the legend of the Owls twins ?They were two earthlian siblings : a brother known as Delita who practiced Necromancy , and a sister remembered as Tetra who studied Herbology .Legend has it that , while exploring the third stratum , the brother went insane and murdered his sister , before committing suicide . The legend tells of their ghosts haunting the labyrinthine halls of the stratum , killing anyone who wanders into its clutches . *** A very ... very late Halloween celebration ... I don't own Etrian Odyssey 5 , Fetid Necropolis , or the classes or jobs that appear here , they belong to Atlus USA .
