Her?
She's aaaa Chronomancer;
If you're ever to wonder why she keeps her face covered, the reason to it is heavily linked to Chromomancy. The term "chronomancy", stemming from the Greek word chronos (meaning time), and the word manteia (meaning divination) is also used in fiction to refer to a school of magic involving supernatural manipulation of time. While her ability is limited, she does posses the skill to slow time. Come in contact physically with her eye, or perhaps stare at it too long, you might find things.. slowing.. down. Only for the connect-ee. Time for anyone else, or herself, remain the same. Not slowed, or sped up. It lasts until she so-decides to cover that eye up, or something such as immense pain, or outside contact such as shoving or covering of ones eyes occur. It really is as simple as looking away, but by the time your slowed self manages that, it may be too late!
