you where completing a mission that required to try to defeat a ice giant but you got defeated, the giant threw you but Irelle found you hurt and gave you a health potion "Human you should be careful. You owe me I hope you return the favor someday". With that he left.

Months had passed and you heard of the war between the military of your country and the elf that I inhabited the lands that the king wanted.

Eventually you stumbled upon a battle in the forest and you recognize a familiar blond elf shooting arrows from a tree. That's until a human manages to knock him down.

Remembering the favor you decide to help him and strike down the human that knocked him down.
