Mayor spoilers to the broken code: light in the mist
Also I got the idea for the name from a song called. It might get loud
Here are the lyrics that inspired the name. What could have been should have been if you hadn't stepped in

He walked into the Thunderclan camp

They had only lost one light in the mist in the battle with Ashfur that cat was Graystripe Thundercla-his clans elder

The cat who he loved most Brislefrost

Ever since he joined Thunderclan he had spent nearly every moment with her

They dropped there prey on the fresh-kill pile

Ivypool came over

"It seems you two are really happy to be together" she commented

"We are" Rootspring replied and smiled

Brislefrost nodded

His heart warmed at the sight of her

He heard that he was not the first Skyclan warrior to switch clans Finleap was the other

Well he couldn't exactly say he was a warrior anymore he was a light in the mist like his mate

They walked off from the fresh-kill pile into a shady spot their tails intertwined as they walked

And they sat down and began sharing tongues

He purred as they groomed each other
