[Runsaga] Ask Me Anything to get the juices flowing

Hi! I'm developing a world based on the concept of "norse mythology meets shōnen anime". It doesn't have an in-universe name yet, but it's the stage of a story titled Runsaga. A story about fighting fate and deciding your own path in life, as well as the causes of violent conflict.

The story follows a young man named Leyf, as he discovers that he's a Hero, gifted with high amounts of Wyrd energy and thus capable of supernatural feats, and joins the High King's army to help defend the people of Aldaheim from the Demons who plague them.

The story uses tropes and character archetypes from shōnen fiction, hopefully with enough personal spins and twists to make it all interesting.

I'm in a bit of a rut with the worldbuilding and the writing, so if you have any questions regarding the setting, the plot or the characters, please throw them at me. I'll try my best to answer these questions in a timely manner. That oughta get the creative juices flowing again.
