Schick, as the head of design and development at TSR, brought aboard Tom Moldvay and David Cook and many other new employees as TSR continued to grow in the early 1980s.[4]:11 Schick created White Plume Mountain in 1979, an adventure module for the Advanced Dungeons & Dragonsfantasyrole-playing game, published by TSR in 1979; the adventure was incorporated into the Greyhawk setting after the publication of the World of Greyhawk Fantasy Game Setting (1980).[4]:24White Plume Mountain was ranked the 9th greatest Dungeons & Dragons adventure of all time by Dungeon magazine in 2004; one judge, commenting on the ingenuity required to complete the adventure, described it as "the puzzle dungeon to end all puzzle dungeons."[5]
In 1981, he contributed to Chaosium's multi-system box set Thieves' World based on Robert Lynn Asprin's anthology series of the same title.[6] The following year, he coauthored the TSR science fiction RPG Star Frontiers with David "Zeb" Cook.[7] Schick wrote the book Heroic Worlds: A History and Guide to Role-Playing Games, which was published in 1991.[8]
Under the pseudonym Lawrence Ellsworth, Schick began translating The Red Sphinx, Alexander Dumas's late-career sequel to The Three Musketeers. He continued his work with The Three Musketeers itself, published in February 2018, before deciding to provide modern English-language translations for the full trilogy of The d'Artagnan Romances as well as the two novels of The Count of Moret in nine volumes.
