@supertinykingOnce they leave it simply sinks into the abyss and rises to the uppermost point it can, sitting down to let it's senses stretch to their limits before it detects three things of interest: a great and ancient soul, more ancient than the land it was in. Twin souls of light dancing about each other, each weak but together they're as strong as the soul that had been snatched from he creature. Finally, there was the soul of a great archer, blinded by jealousy... literally rather than metaphysically.
The first point of interest the creature heads towards is the ancient one, it's flight through the canyon becoming obvious upon arrival before it too notices it's opponent and begins a circling manuver and prepping for an attack only for it's jaw to be speared along with it's head, it's body being crashed down to the earth before black flames envelop the insides of it's skull, scouring it of it's brain and killing it painlessly before it's soul begins to hover above the corpse, the creature grabbing it before sinking it into it's skin, a black and red metal egg comeing back out before the creature takes some time to hollow out it's head to use as a storage space for the 'egg'
