Other mistake: In the picture of Twig's woodtroll village (Corgi edition page 291), it shows the village with a large tree cabin in the middle. At the bottom of this tree, you can see Twig and Cowlquape standing with a small figure that is probably an oakelf. We can assume this oakelf is Spooler because the only other oakelf is Taghair, who is in his caternest. If the figure is Spooler then this is a definite mistake because Spooler died in the last chapter. Twig and Cowlquape should be standing with Goom the banderbear.
