Moonspear the very best, that no one ever was

Combat oriented indeed. But her mother was teaching her how important it was to be as swift as she was, well, aggressive... and even her father was trying to impress this upon her. These exercises with Lyra would help her, as at present Lyra was, in fact, the swiftest of them. Alya took hits gracefully; Lyra fled them when she could, and she did so better than any other in Hydra's life. Hydra would become them all—a fierce, aggressive savage who could take a hit, dole one out, and avoid blows when necessary. She wanted to be quick enough to deliver them to those of her physique, which meant learning with Lyra. Of course Hydra would never really hurt her, but she did want to catch her. 

The laugh was one Hydra understood meant something was up. As Alya and Lyra would know the darkening of her features meant an imminent strike, Hydra would know when her sisters were playing at something, anything—they were of the same cloth, and she had memorized the patterns as no one else (bar themselves) would ever be able to do. Her sisters feint was more than humored—that was something new for her sister, likely learned from their parents or even her own self when practicing... but Hydra would regain the ground lost! 

Hydra bounded after Lyra, weaving through the trees and leaping over any debris in her path. She practiced parkour used a tree to bounce off the side of once her sister was in sight again, and Hydra stretched out her legs to lengthen her stride.
