Professor Codex

Professor Codex is a bird-like librarian of the Great Library. He appeared in Bookworm Adventures 1 first as a mentor to Lex. When Cassandra was kidnapped(at the end of chapter one,mind you),he told Lex it was dangerous to go and retrieve the poor girl. He is also kidnapped in the middle of the game. In a specific stage in book 3 or chapter 3,the boss told Lex that the latter was dead(there were also tombstones bearing their names). The event will cause Lex to discover the tomb of heroes where he will get his courage back(he got discouraged in the level). In the end, it was revealed that Codex was behind the troubles in the game. He was the one in the cloak all along. Their showdown takes place in the library where he summons 4-5 bosses from the chapters. after you finish them of,you have to defeat Codex and his three rows of hearts.After his defeat,he will boast that he can destroy Lex once and for all. Before anything else happened, Lex spelled a REALLY LONG WORD,vanquishing the evil professor and putting him inside the magic pen.
