Deletion of Erreth-Akbe

Comment: Erreth-Akbe is discussed in Hart and Slovic's ''Literature and the Environment'', in Phillis Jean Perry's ''Teaching Fantasy Novels'', and in Michael Faerber's ''A Dictionary of Literary Symbols'', as well as in peer-reviewed articles by Manlove (1983), Hatfield (1993), and Trębicki (2011), among others. Certainly enough to satisfy GNG and demonstrate "notability outside the book universe". |AFDISNOTCLEANUP
