Yegor was a dwarf, mentioned to be "in critical condition" in Book 4: Neverseen by Mr. Forkle. He later was found out to be dead. Mr. Forkle had also announced the deaths of Irja, Kun, and Ermete at that time. Yegor presumably passed away in the battle on Mount Everest during the events of Book 3: Everblaze. Yegor appears in Book 3.
