Rockkit was the youngest kit of Sparrowkit and Firkit, to their parents, Blackcloud and Tigerblaze, the first litter.
After admiring Poppynose and her herbs, Rockkit chose the path of a medicine cat. Enjoying it, he decided to stay and learn about herbs and how to use them to heal cats.
Becoming a full med cat
During a visit to the Nightpool, Poppynose gave Rockpaw his full name, Rockpool. After this he had a good destiny, except for one part, when Poppynose was tragically killed by a rogue cat.
Earning an apprentice
When Marshkit, Rainkit and Hollykit were born, Rockpool was pleased when Marshkit told him he was interested in becoming a medicine cat, so when he was apprenticed, Marshpaw became his apprentice.
When Marshpaw was ready to earn his name, Rockpool was killed, by a rogue cat, the night before Nightpool departure, so Rockpool named him in his dream and is now known as Marshrunner.
Rockpool was a dark grey tom with green eyes and a bushy tail.
