Sage was a slave use to fight against bigger and better animals, finally brought to his death by a lion. He became a sort of folk tail of warning to obey your parents or you will be sold to the government and suffer the same fate (dude Spanish parents do this a lot-) A part of the story says you can summon him if you say his name “Sage the slave” 5 times. A group of a wolf, a cat and a bird decided to do it,
They succeeded in summoning Sage, only for him to run away in fear, and live in the woods, overcome with PTSD and anxiety.
