A few days earlier, Alaric's POV:
Alaric Sonora was a peak fourth-stage disciple of the Divine Sword Sect. He wasn't a normal disciple; he was a core disciple and reached his current stage when he was only 27. His foundation was firm as well, and he never cut corners in his training.
His master asked him if he wanted to enter the secret realm of the Bloodthirst Sect. Apparently, there was a big story about a child that slaughtered the disciples of the Four Seasons Sect.
When that happened, Alaric was cultivating diligently in seclusion, so he wasn't there to watch. Most of the core disciples were cultivating in the sect during the war since no elder wanted to take the risk of having his personal disciple die.
Most of the war was fought between the inner disciples, outer disciples, and the ones both sides brought from other sects. It was also the reason that Ken didn't fight a single core disciple from the Four Seasons Sect.
