Theron's Quest is an adaptation of Dungeon Master for the TurboGrafx / PC Engine console. The Japanese version was released first in Japan on September 18, 1992 and later the English version was released in the USA in 1993.
I gathered the Theron's Quest reference information you will find on this site by playing with the English version of Theron's Quest.
Although it has a new story, it is rather a "light" version of Dungeon Master. For example, Theron's Quest only contains subsets of the items, creatures and spells found in Dungeon Master. And instead of one big dungeon where your team of four champions venture from top to bottom, gaining experience and getting items, Theron's Quest contains seven small dungeons, some of which have parts copied or inspired by the original dungeons of Dungeon Master and Chaos Strikes Back. You play the game with a character named Theron and three other champions. These three champions lose their skills and items upon completion of each dungeon, and the game is only saved between dungeons. Theron also loses his items between each dungeon, but keeps his skills and statistics.
This all makes the game less interesting than Dungeon Master, because you don't have the time to train your champions and to use all the items you may find. Because you can't save the game, the designers have put many Altars of VI to resurrect your dead champions, and not much creatures to fight, so the game is very easy (on the other hand, you don't have to play a dungeon several times before being able to finish it in a single playing session, which is not bad after all).
The goal of the game is for Theron to retrieve the seven following valuable items:
Each of these items is located in one of the seven mini dungeons:
