Shortly thereafter TLG published the Codex of Erde[2] (later Aihrde), a fantasy world campaign setting and sourcebook for RPGs.

Stephen Chenault recounts the origins of the Codex of Erde and how they were enmeshed with the founding of TLG as a company, in The Crusader Magazine.

2008 saw a new hard cover release and reprinting of the Greyhawk Adventures book Saga of Old City,[6] a Gord the Rogue novel by Gary Gygax.
