Bem, eu sei de apenas uma história que se encaixa nisso e foi a Guerra do Irmão , um romance de Magic the Gathering. No entanto, a primeira impressão do romance foi em 1998 ... tão provável não se encaixa na linha do tempo. Não tenho certeza se os quadrinhos foram ainda mais tarde.
Urza and Mishra are brothers living and working in the Fallaji desert under the tutelage of their mentor Tocasia, an archaeologist. Born in the same year but on the first and last days, respectively, the brothers frequently clash but are united in their curiosity about the Thran, the ancient race that left behind the artifacts Tocasia studies. In AR 20 the brothers and Tocasia discover Koilos, the secret heart of the Thran civilization. There they find a Thran machine with a large and powerful powerstone but when Mishra and Urza reach for the stone it explodes, splitting into two halves. Urza demands to see Mishra’s half but the younger brother angrily refuses and the two have a falling out. They discover that Urza’s stone gives machines strength while Mishra’s weakens them so Urza names them the Mightstone and the Weakstone. Later on, a drunken Mishra confronts his brother and the two fight using their powerstones. Tocasia tries to intervene but when she comes between them the area explodes, killing her. Horrified, Mishra flees and the excavation site is closed....
