"A great cat sits upon the northern grasslands, my friend, waiting to pounce on adventurers just like you." As you part the tall grass with your sword, the words of the tavernkeeper echo in your head. "He was the mightiest wizard we'd ever known, and that Lion Castle was his home." Your friends' voices mingle with the tavernkeeper's. "He's but a ghost now, haunting those halls, and waiting for an heir." The ground rises slightly. A strong wind rushes through the field. Suddenly, the grasses part, and Lion Castle rises majestically before you! "Magical riches await those who enter!" "Beware of man-beasts!" Voices flood your head again. Will you brave the haunted castle? Can you afford not to? It's all up to you in this D&D Solo Adventure. Ghost of Lion Castle is for one player only, but that one player makes all of the choices and enjoys all of the rewards. An entire castle and courtyard await your exploration. The adventure also includes a complete solo combat system. TSR 9097

The valley of Haven was a peaceful land. Its crops were abundant, its citizens prosperous. Elves, Dwarves, Halflings, and Humans lived together in harmony. Hidden away in the heart of the Thunder Mountains, Haven was a safe place to live. The rivers were sweet and pure; the weather was pleasant and warm. Something terrible has come to pass in Haven - terrified refugees speak of a fabulous ruby uncovered in the mountains and a catastrophe that befell the palace. Whatever the cause, Haven now lies in chaos. Raiding bands of orcs, goblins, and hobgoblins terrorize the countryside. The disaster happened so suddenly that the citizens are confused and helpless. Without their leaders, who are trapped in the palace, they have no courage to fight back. The situation has become desperate. TSR 9044
