Like the title says this is a Warriors X Sonix au but this specific story doesn’t tie directly to a part of the Sonic lore (other than the echidna tribe being wiped out). Admittedly, it’s more of a warriors story than a sonic story.

The story follows Red-Bristle (Knuckles) as he attempts to cope with being the last surviving member of his clan (Cloud-Clan). As a result, he dreams of how different his life could’ve been if the flood that wiped out his clan had never happened. Here, he dreams of finding a mate, a she-cat named Poppy-Dream. She’s kind, soft spoken but intelligent and funny, and she’s the deputy of the clan! The two of them end up having 4 kits, 3 Tom’s and a she-cat who looks just like Red-Bristle! He can’t imagine a world where he’s happier! Bit, a single raindrop pushes through the cover of the warrior’s den, falling on his nose, and waking him, leaving him to remember how miserable the waking world is for him.

Don’t worry! He does find happiness eventually! He just has to go through some shit before he gets there..
