What had happened was all on the ruby's power, which helped to control and manipulate Peregrine's. Once Peregrine touched the ruby, four figures appeared around him. These figures were invisible, to the human plane generally. Only Peregrine could see these four figures. Each of these figures looked like oversized humans that were almost skeleton, skinny female giants. Each of them wore silky cloaks that covered their heads and wrapped around their bodies, revealing only their almost skeleton faces and long black hair tucked under the hood of their cloaks, part of their hands from.the elbow to the fingers and their foot.
To put it simply, they looked like female death gods.
They wielded two scythes akimbo each, with beads around their right arm. All four of these figures floated around him on standing. Peregrine called these floating souls Smythes.
