The ScarfBearers design is that he has the ability to use his scarf that envelopes his body as if it were his arms. After he merged with a magical orb that melted his one arm permanently to his side and evisirated the other arm in the process, he is left only with one eye enhanced with an ocular device and the Scarf Bearing ability.
Inspired by this photo I took of my friend whilst watching a sunset at Granger Bay, Cape Town, South Africa. He was on a call at the time and an angle appeared where his arm was seemingly embracing the Sun. The overwhelming glare made this silhouettes appear to be one melded shape.
