5.44.n-Roland

Already I could see the Rogue Sorcerer’s face was flushed and dripping with sweat, his breathing hard. Mages like Masego and Akua, who used the exact amount of power needed to make a spell function to the intended purpose, would be able to continue throwing around sorcery for longer even if it was of higher calibre. Roland, clever as he was, was bleeding power well in excess of Keter’s Due and I suspected his natural gifts weren’t particularly impressive besides: if he continued at this pace for much longer, he was going to fall unconscious.
