The images were that of a group of three youths who looked slightly older than Sol. One was female while the other two were males.
This shout was from the boy that was attacking a ferocious-looking beast with the girl.
The beast itself was quite large, and it look like a mix between a lion and a polar bear with its pure white fur. However, this pure white fur was dyed red in blood from the beast's wounds.
The shout from the boy attacking the beast was directed toward the second youth that was seated cross-legged away from the battle.
This youth was busy forming hand signs, while in front of him floated an illusory sword that was continuously releasing powerful ripples into the surroundings; which caused the void to tremble.
Sol couldn't feel the strength of this illusory sword, but from the beast's already injured state, it would die if it was hit by this sword.
