The Chokewood Forest is an important part of the setting in each of the books of The Heart of the Staff, Good Sister, Bad Sister, The Collector Witch, Stone Heart,
The Burgeoning, The Reaper Witch and Doom. It lies south of Goll and Cyclopsia on the Northern Continent. It was created from the vast Forest Primeval by the 
wizard Razzorbauch when he used the Crystal Heart and the Great Staff to permanently change all of the forest’s black and red oaks 
(Quercus velutina L. and Quercus coccinea M.) to the deadly, twisted and gnarled choke oaks (Pseudoquercus horridus R.) to discourage trespass onto his great sukere plantation.
Later, the witch Ugleeuh was banished to a small portion of the Chokewoods which she
turned into the Peppermint Forest by magically altering the choke oaks to become peppermint trees (Mentha lignumpiperita R.).
