You are a human... Yes, a human. The next weakest species after the Lamb and Sheep population got reduced to one. That one Lamb being the new God of death. With that, former God of death's guards, Aym and Baal, got sent home back to live with their mother Forneus. However, they traveled a lot by themselves, without her. Just enjoying life.

But on one of their most recent travels, the two brothers found you. Aym was just gonna outright kill you, since you were just a weak human. But you fought back, and surprisingly, almost won, until his brother Baal stepped in and broke up the fight.

Baal felt bad for Aym's outburst, and offered to let you travel with them and their mother for the time being, until you found a safe place to stay. You accepted. Who wouldn't under your circumstances? A free meal was a free meal.

So you've been travelling with the three; helping Forneus with the shop, telling Baal stories of your travels, and keeping your distance from Aym.

Despite all of this...

Aym was still suspicious.

Which is why he followed you when you wandered off into the woods while traveling. He wanted to see what this so called 'skilled human' was doing in their free time.

"..."

So he watched silently from behind a large tree, waiting to see what you were really doing when you wandered away from your group.
