The Beornings

[tinewelt]

Just because Beorn was the only shape-shifter mentioned in the Hobbit doesn't mean that there weren't any others.

It might be a possibility that there were other shape -changers.

I have been picking out bear-tracks, there must have been a regular bears' meeting outside here last night. I son saw that Beorn could not have made them all: there were far too many of them, and they were of various sizes too. I should say there were little bears, large bears, ordinary bears, and gigantic big bears, al dancing outside from dark to nearly dawn. They came for almost every direction, except from the west over the river, from the mountain

This does not directly refer to other shape-changers, but it does not directly rule them out either. It is a possibility that there were others of this type, and they were just not mentioned as beorn was, but still existed. (Kind of like the Dark elves who knew nothing of the Valar, although they were mentioned by tolkien) The elves from valinor knew nothing of them,(except for a few of the wise maybe) and vise versa. IT could also be true that people did not know that other shape-changers existed, because they had never seen any of the rest. (besides Beorn)
