Sagepuddle is a StormClan medicine cat, still learning under her mentor, Hollowstep. She is pursuing a relationship with Ebonymoon. She presents herself as serious and distant, although is quite goofy and relaxed with those she trusts.

As a medicine cat, Sagepuddle is a bit strange. She's very interested in the morbid aspects of the job, unusual for a medicine cat.

Sagepuddle is an unsually small white-and-gray tabby she-cat with pale blue eyes. She has very fluffy fur.
