Nightwhisper

Nightwhisper is a black tom with greenish-yellow eyes.

Backstory
Nightwhisper and Petalspot were found by a Twoleg couple. Nightwhisper, at the time, was named Dark Knight, a nickname for him being "DK", and Petalspot was named Princess.

However, the Twolegs had to move to a place where animals weren't allowed, and so left the two at an animal shelter. A captured MoonClanner bargained with them, and the three managed to escape. The Clanner led them back to MoonClan, and after some time, they were accepted.
