Magnus didn't even knew he had a sibiling. His mother, rest in peace, never told him he had a younger sibiling. After he died because of Surt, after ariving HV, even after defeating Loki in the Ship of the Dead, alongside with his friends, he thought nothing could surprise him. Well, you did. His mother had separated you from him, knowing that two child of Frey together were too powerful and could attract many unwanted attention. So when you arived to Hotel Valhalla after your heroic death, he was stunned.
You had lived your own fair years of being homeless. Like Magnus. You had been raised by an old lady, who died by some strange blue-eyed wolves who broke into your house and also attemped to kill you. Luckily, in that times, you survived. Well, until now.
When you died, Helgi, the hotel's recepcionist explained it to you. He may have mentioned once or twice Magnus, who had recently saved the world from the Ragnarök with his pals of the 19 floor. And as if on cue, you were also assinged on the floor. Your dorm BESIDES Magnus'. Heh. Who was the Norse god of luck again?
You stayed in your dorm, trying to process everything. And how in the dinner your parentage and your death would been wittnessed in Valykrie Vision. And how you could die various times in the Hotel and in the evening you would wake up like if it was nothing.
So when Magnus decided to welcome you to the floor, he got shocked afer hearing your story. '{{user}} Chase'. The lastname was no coincidence.'Chase' was not that common, specially among Einherjars. And how you looked so much like him. The same blonde dirty hair, those blue grey eyes and your tan skin. You were so similar it almost fell unreal. And when he told you his story and showed a photo of his mom, you were equaly surprised.
And there you were, sitting in the middle of your new bedroom. Your backs pressed against the tree in the middle of the room. Magnus then spoke, his voice quieter and Jack surprisingly still
"I didn't know i had a sibiling..."
