About the Project

Threat of the Trinity aims to produce a complete addon 'module' for the original DOS version of Quest of the Avatar, as close to how it might have appeared in a store in 1986. It will add additional content, via quests, locations, and features. It will also avoid altering the original quest content as much as possible, aside from some simple 'refreshment', permitting the game to be completed in the original fashion, whilst still making the new content available. A extensive bug fixes of the original code will also be included. The orignal DOS version of Quest of the Avatar will be required to play Threat of the Trinity.

The Features

New Major Quests

The Threat of the Trinity presents new major quests, the completion of which is critical for the peace and safety of Britannia. Ignore the quests if you wish, or complete them and leave Britannia more safe and secure once the secrets of the Codex have been uncovered.

New Crypts, Caves and Mines

Almost twice as many dungeons, means twice as much adventure! They range from simple cave systems, to complex and fiendish crypts, packed with traps and puzzles to thwart the most resolute of parties. Prepare yourself for the depths...

New Hamlets, Towers and Huts

Many new locations in Britannia and beyond to discover and explore! More than double the number of locations of the original game means twice as much exploration and discovery. Seek them out, and discover their inhabitants and mysteries.

New World Region

An entire new region of Britannia, waiting to be discovered, mapped and measured. This new region is as large as Britannia itself, and will present challenges which push a parties resolve to the limits.

New Minor and Side Quests

New quests await the avatar, which will lead him across the width and breadth of land in search of clues and artifacts. Follow the quests and he will find aid on his journeys, or ignore them and stay focused on the Quest of the Avatar.

Random Encounters

Dozens of random encounters, which range from meetings with pilgrims travelling to shrines, to multi-level ruined cities from ages of yore. Explore them and discover secrets and items which could help on your quests.

Bug Fixes and Improvements

More than 30 bugs fixed, making the Threat of the Trinity the smoothest Quest of the Avatar experience yet. Many small improvements to combat, realism, and balance hone the game. For a full list of fixes and improvements, see below.

Multi-story Towns

Nearly every castle, town, village, hamlet, tower, hut and inn now has multiple stories above and below ground. Explore Brittannia in more than two dimensions. The third dimension is here, and will bring a new...depth, to your Quest of the Avatar experience.

Warriors of Destiny Style Features

Some of the best features of Warriors of Destiny, included with Threat of the Trinity now! Mix multiple batches of reagents, use Active Player to more easily explore complex dungeon rooms, and attack and search in any direction around the player.

The Feelies

Apple II Big Box

An old school 'Big Box' scaled to the exact same size as the Apple II and C64 versions of Quest of the Avatar and Warriors of Destiny. Beautiful artwork in a new but familiar pattern set the tone for the addon. It will fit perfectly in the shelf between both of its brethren.

Cloth Map

The cloth map was ubiquitous in the 80s RPG series, and Quest of the Avatar was no exception. So Threat of the Trinity should include one too. A new map for the addon, which will expand ever so slightly on the original, add some missing features, and take its place in the pantheon.

Quest Journal

Record your adventures in the journal, to keep track of conversations, clues, locations, and dungeons. Pages will be reserved to gather the wisdom of town inhabitants, and make connections between them. Other pages will be ready to record and map your delvings into the darker caves and crypts to be encountered.

Player Reference Card

Like the Reference Card of Quest of the Avatar and Warriors of Destiny, Threat of the Trinity's will be filled with the basic info you need to get going with the game. Heed its advice, and your party will surely prevail against the Threat, and in the Quest.

Quick Reference Card

Keyboard commands are one glance away. Attack and Defence values of weapons, armor, and terrain are laid out for quick reference. Spells, which may take some time to memorize the reagents for, are organized and detailed for the budding spell-user.

Trinket

A metal ankh denoted the Quest of the Avatar. An important object from the game, which could be held in your very hand. What will the Threat of the Trinity provide. Perhaps an artifact, such as the Skull of Mondain?
