Lichen is a mottled brown she-cat.[source?]
In the Super Edition Arc
- Lichen is a loner who is friends with another rogue, Scratch. After Scratch and Firestar tell her about a meeting where cats could learn about SkyClan and Clan life, she agrees to go.
- Lichen goes to the meeting, but is too shy to join SkyClan. She refuses politely, but firmly, and wishes them well, saying that she doesn't feel comfortable around such a large group of cats. Firestar seems particularly dismayed when she rejects the offer to join, for he thinks she would have made a good warrior.
- Later, when the Clan is deciding where SkyClan's borders will be, Sharpclaw suggests that they make the stream one of the borders, so that Lichen and Rainfur's dens would be outside of SkyClan territory, and therefore they will not be disturbed or have to fight over prey with the Clan.
