From the introduction:
The Lyceum is a short Dragonlance adventure. It is designed for player characters of 5-7 level fighters and 3-5th level magic users and clerics. All other character classes should fit between these ranges. A part of 6 to 8 players is recommended. It may also be important for the characters to include at least one character of every alignment.
The adventure takes place after the fall of the Queen of Darkness in the War of the Lance in the land of Nordmaar, more particularly of the east coast of that place near the ancient ruins of Valkinord.
The adventurers have come to this place, as explained in the introduction scripts, with manifold purposes. The ancient Lyceum - a school for the first levels of Wizardry and a repository of magical knowledge - has remained abandoned and isolated since the cataclysm. During the War of the Lance, however, it was occupied by a small force of Draconians. When the Queen of Darkness fell, one of the Dragon Highlords repaired to this place with a Priestess of Takhisis (the queen of darkness) and a Black Robed Wizard. Though there armies moved in and have placed the countryfolk under cruel oppression, there has been little to enrage them until now. During the last week, however, six people have disappeared from the neighboring town. They were very unlike the usual brute incarcerations carried out by the draconian patrols. These took place quietly. Now, great black clouds boil out over the countryside from the Lyceum and, mysteriously, most of the draconian forces have suddenly removed themselves some distance from the place.
One of the prisoners managed to escape. Crazed and near death, he continuously babbled about what was happening within the walls but made little sense. His words however galvanized action against the Lyceum. In the end, the adventurers will discover (1) what happened to all the worthy clerics at the time of the cataclysm and (2) that the Highlord is trying to reopen the gate to the Abyss just as was done anciently. This second discovery threatens the first and it should become clear to the players that they must stop the Highlord at all costs.
User summary:
The Lyceum widely circulated as an ASCII text file from ca. 1996 onward. It often was included on "bulletin board" and fan sites of game materials. The file is well-formatted, with locations of intended images noted, etc.
