Into the Troll Realms

Into the Troll Realms, subtitled "Troll Adventures and Encounters for RuneQuest" is a supplement that includes adventures and material that involve interactions with trolls, published under license by Avalon Hill in 1988 for Chaosium's fantasy role-playing game "RuneQuest" 
Description.
"Into the Troll Realms" includes three "RuneQuest" scenarios in which the player characters must interact with trolls:
The book also includes three small encounters that can be played on their own or integrated into the larger adventures, as well as the rules to the game "Trollball"; this material originally appeared in Chaosium's 1982 publication "Trollpak".
Publication history.
Chaosium originally published the fantasy role-playing game "Runequest" in 1978 set in the fictional world of Glorantha, and quickly followed this with a second edition the following year. In an attempt to increase distribution and marketing of "Runequest", Chaosium made a deal with game giant Avalon Hill in 1984 to publish the third edition of "RuneQuest". Under the agreement, Avalon Hill took ownership of the trademark for "RuneQuest", but Chaosium did not include the setting of Glorantha in the license unless the content was either created or approved by Chaosium staff. If Chaosium did not supply Glorantha material, Avalon Hill used a generic setting called "Fantasy Earth". 
"Into the Troll Realms" is one of the Glorantha-based supplements supplied by Chaosium but published by Avalon Hill in 1988, a 48-page softcover book written by Greg Stafford and Sandy Petersen, with interior art by Daniel Brererton, cartography by Charlie Krank, and cover art by Steve Purcell.
Reception.
In the August 1989 edition of "Dragon" (#148), Jim Bambra complimented the authors for breaking away from their usual combat-oriented material, noting "By describing trolls in their natural habitat and by allowing PCs to interact with them through role-playing, rather than through violence, "Into the Troll Realms" clearly shows how trolls can be used as colorful and interesting non-player characters." Although Bambra thought that all of "the adventures are of a uniformly high quality and emphasize role-plyaing over combat", he especially liked the third scenario, "Flying Trollkin", calling the encounter "excellent, it builds steadily in atmosphere and gives us neat and evocative images of how trollkin think and act. Surprisingly, this is achieved in less than one page of text." He concluded with a strong recommendation, saying, "Grab a copy for inspiration and to enjoy some excellent monster-oriented encounters."
