- -Arboretum Sicklebough
Arboretum Sicklebough was the Hall Master of Storm Cloud in the Knights Academy. He was a Tree Goblin, and gambled his money foolishly on Fromp-Fights. Due to his gambling debts, Arboretum Sicklebough was often ill-tempered. He was kicked out of the Knights Academy by Hax Vostillix.
The word "arbor" means tree in Latin, and a "bough" is another word for a branch, making Arboretum Sicklebough a very fitting name for a tree-goblin.
