Summary
Din is having a great day; Grogu is sick, Paz is arguing with Bo-Katan again, and The Armourer has locked herself away in her forge for whatever reason. Not to mention all of Mandalore has decided today is the day to have a crisis.
He should have expected today to get worse when the Darksaber started talking in riddles, and reports of six sickly looking children biting people started turning up on his desk. Honestly, he really should have connected the dots sooner.
--
John-117 was having a great day. Being tossed through a portal onto a random planet, with two of his (now alive) dead teammates, and his four traumatised SPARTAN companions. He was also on the verge of a mental breakdown.
Sam-034, meanwhile, was having an argument with the voice in his head, which seemed insistent on him learning a nice sounding language called Mando'a, and trying to get him to sleep a full nine hours.

Summary
Cassandra opened a door that was clearly heavier than any of the others they had passed through, leading to the outside. Cold air swept into the stone structure, as six caught a glimpse of snow covering the ground outside. Six’s eyes struggled to adjust to the nearly blinding daylight after the dank darkness of the dungeon, but once they had, Six looked around to get a sense of his surroundings, and…
“Holy shit.”
Noble Six, AKA SPARTAN B-312, AKA Maxwell Trevelyan should definitely be dead. Left to die on a desolated planet, glassed by the covenant, there's no rational way to explain his survival. But fate has other plans. Tossed into an unfamiliar world stuck in the dark ages, filled with demons, magic, and holes in the sky, with no UNSC in sight, Six is put to the ultimate test. And maybe just finds that he's not quite so alone, after all.
Alternate Title: I'm going to give this man a family whether he wants one or not
