The Rats
Listing every member of the current rat colony Morris travels with would be a sisyphean task due to the constant births, deaths, and individuals departing to join other colonies. A few members are detailed here, and other key rats he has encountered are as follows, from oldest acquaintances to newest.
Fruitcrumb
The first rat Morris spoke to. A small, anxious young buck whose colony was destroyed by the ratcatchers, mostly through the use of poison. He escaped and found the Druid Circle, where he remained to recover from his experience.
Butter
The alpha rat when Morris was trying out his "embark upon a ship to escape scrutiny" idea. Boasted a talent for escaping a tight spot unscathed. Butter was far more wary of Morris than Fishstinky, and the colony under his guidance was much more distant, which caused more than one frustrating incident for Morris. They parted ways after the final fateful voyage, when Butter elected to remain behind on the island they were deserted on.
Pawdamp
A dam who chose to leave the island with Morris and provided the basis of the new colony he now travels with. One of her pups, Fishstinky, was born aboard the ship they escaped the island on.
Fishstinky
The current alpha rat. Medium-sized, rather scrappy and scabby around the edges. In terms of personality Fishstinky is, as one might expect, rather bossy, a necessity to maintain his position, but unlike Butter he has total trust in Morris and considers him an equal. He's also more open-minded to Morris's requests.
Grapewood
A doe adopted into the colony after Morris rescued her from the Skullduggan family cat. Not only did that become a diplomatic incident in miniature as Morris attempted to reason with both cat and rat, to the intense amusement of the Skullduggan Twins watching through a keyhole, but Grapewood is descended from the rats who escaped Morris's poison a decade ago, creating a complex, conflicted relationship with her saviour. At least explaining the intricacies of the situation bored the Skullduggans enough for them to lose interest in feeding Grapewood to the cat.
