Grim was the strongest arena fighter in Anatol’s past, a dual-affinity combat fanatic who wielded both Fire and Yorunia’s stolen Water Cell. Despite his brutal love for battle, he showed selective restraint, protecting Yorunia during her lowest moment—unintentionally binding her to him emotionally. His eventual defeat at Dina’s hands marked the end of the arena’s golden era and triggered the chain of events that led to Anatol’s current conflict, particularly through his connection to Chief Gorsch.
