A bad god's guide to making enemies

 
Loki has made a fair few enemies during his time in Asgard. Too many to count and certainly too many to remember. When the elf, Vinir beams Loki aboard his chariot and challenges him to a magical duel, Loki hasn't got a clue why. Sweet talking his way out of a fight by pointing out there's little honour in duelling someone who can't remember how they wronged you, and even less in picking on a child, Loki is returned safely to school. That is until Vinir shows up in child form, as resolute as ever about seeking that duel ... and vengeance.
