* FountainOfExpies:
** The very first Literature/{{Discworld}} novel, ''Literature/TheColourOfMagic'', features a cameo by "Bravd and the Weasel". Not to mention the city of Ankh-Morpork, in its original form similar in both name and description to Lankhmar. In later books it developed its own unique character.
** ''ComicBook/ConanTheBarbarian'' #6, written by Creator/RoyThomas and published by Marvel, was set in the sinful city of Shadizar, which as written by Thomas owed a lot to Lankhmar, and featured a cameo by "Fafnir and Blackrat". (Shadizar came first -- it's a Zamoran city from Howard's original stories -- but Howard never developed it much, though it was definitely a WretchedHive.)
** ''Comicbook/{{Fables}}'', starting from issue #77, features obvious expies of the two called Freddy and Mouse.
** Literature/{{Otherland}}: The digital avatars of Orlando Gardiner and Sam Fredericks are expies called Thargor and Pithlit.
* OutlivedItsCreator: After Leiber's death, Robin Wayne Bailey wrote the authorized novel ''Swords Against the Shadowland'', which takes places between the first two books of the series.
