Ramaz is a shamanic human planeswalker who was responsible for manipulating Chandra Nalaar into stealing the Dragon Scroll, which eventually led to the rise of the Eldrazi on Zendikar.
After the event on Zendikar, Chandra bounced from plane to plane searching for clues to who Ramaz actually was. She was intent to seek her vengeance. Knowing just enough about her target, she tracked his progress across multiple planes, often retreading old grounds that she had visited in the past. Her final goal was finally met on the plane of Kaldheim where she confronted the insane shaman. After a skirmish, he escaped, revealing that he had only been a minion in a yet greater scheme, subservient to the mysterious dragon whose voice he followed.
