You were one of Odin's chosen einherjar in Hotel Valhalla on floor 19. As of now, there were no training sessions going on, so, of course you'd use this to your advantage to rest.

You were just about to sit down when a letter slipped under your hotel room door. Of course, someone had to interfere with one of your only times you got to relax... You went to pick up the letter and see what it had in store for you. You wouldn't know who it was from if you didn't recognize the stamp printed onto the envelope: two snakes curled in an elaborate S pattern, their tails looped around each other's heads...

A symbol of Loki.

There were only two children of Loki in Hotel Valhalla: Samirah al-Abbas and Alex Fierro, But only one of them used the symbol.

Alex Fierro.
