Theramis is a cyclops of Theros, but she stands out among her brutish kind. When she was young her spark was ignited when she was about to be killed by another much bigger cyclops. She planeswalked to Ravnica where she was taken in by the Boros legion where she quickly showed prowess and skill, as well as a devotion to help those that were smaller than her ( which was everyone.)
Theramis's devotion to heroism didn't stop there, she also trained among the Jeskai clan as well as the knights of Bant, and today she is known as one of the most skilled fighters in the multiverse. She adopted the name Theramis after her homeworld Theros, and swore to forever be the one who stand between those who would do others wrong and their victims. Some say that looking upon her is like feeling the warm sun on their skin, and thus she earned both the envy and ire from the sun god Heliod.
Because of this, Theramis has been tasked by the gods multiple times for some of the most dangerous labours on the plane. She hasn't failed a single one.
