It hung behind him like a massive, perfect sphere of ice, cold mist streaming from its surface in ghostly wisps.
Northern studied his own body, noting what freezing the sun had done to him.
His form had changed completely from what it once was. Being able to connect with the world around him at a deeper level meant he could tap into several of his talents and their powers, especially the elemental ones.
This meant some reactions from Northern's elemental talent could directly touch his body. Or to put it more clearly, his body could drink from the benefits that flowed from it.
Extreme cold made the body brittle and stiff, slowing it down like rusted metal. That's why Northern hadn't relied on just the ice side of his talent.
That's exactly why he had frozen the sun. While he wrapped FrostHeart around Sun Legacy, the latter still burned bright and kept strengthening his body.
