Heath was one of two twin squirrels in the Circle that saw truth in Crispin's case during his trial and subsequent exile from Mistmantle Island by King Brushen at the behest of Captain Husk. Heath was described as being shorter than Russet.

Heath helped Arran stack lumber whilst Russet led the landslide prevention precautions, and later commanded the defences with Urchin at Curlingshell Bay
