You began your Quest for Glory as a graduate of the Famous Adventurer's Correspondence School for Heroes. A poster in your local Adventurer's Guild read, "WANTED: HERO. NO EXPERIENCE NECESSARY. VISIT BEAUTIFUL SPIELBURG, FIGHT MONSTERS, DEFEAT BRIGANDS. REWARD AND TITLE 'HERO OF SPIELBURG' TO THE SUCCESSFUL APPLICANT".
It sounded good, especially the "no experience necessary" part. That was before you learned that being a Hero meant fighting vicious monsters, solving puzzles and evading traps, having to walk miles through the trackless forest, and generally working your tail off. As you rescued the Baron's children -- Elsa and Barnard -- from enchantment, you learned that the brigands were only part of a larger problem. The Baron had offended Baba Yaga, a powerful Ogress, and her curse had caused disaster throughout Spielburg valley. Only when you used her own magic against her to drive her out of Spielburg was the land once again free from her enchantments. During the course of your adventures, you learnt of the great spellcaster Erana and made friends with the powerful Archmage Erasmus and his wise-cracking familiar, Fenrus the rat. (This story was told in Quest for Glory I: So You Want To Be A Hero.)
Then you traveled with your friends Shameen, Shema, and Abdulla Doo on Abdulla's magic carpet to the mysterious desert land of Shapeir. There you fought against the elemental forces of nature themselves to guard one city and release another from the evil rule of the Wizard Ad Avis. You also made more friends -- Rakeesh, the Liontaur Paladin and Uhura, the Simbani warrior woman among them. The wise Sultan Harun Al-Rashid adopted you as his son for your heroic deeds there (as recounted in Quest for Glory II: Trial By Fire.)
But something went wrong. Although you saw Ad Avis fall to his doom, streaming with flames and calling to his Dark Master for help, the body was never found. The Sorceress Aziza informed you that Ad Avis was certainly dead but that his magic had somehow survived him. Part of his influence allowed a powerful Demon Wizard to break through the veil between worlds to attack Rakeesh and Uhura's homeland of Tarna. Traveling through a magical portal, you accompanied your friends to help stop the Demons from bringing more of their kind into our world and to prevent a Demon-incited war between the Liontaurs, the Simbani, and the Leopard People. (You helped shape these events in Quest for Glory III: Wages of War.)
Even as your friends and companions were congratulating you after your final battle with the Demon Wizard and your closing of the world portal, you were seized by a dark magical force and wrenched away from the land of Tarna. Stripped of your possessions, you awoke in a dark cave in an unknown land.
You managed to escape from the cave of the Dark One and make your way to the isolated town of Mordavia. Problems abounded here too, but you eventually won over the suspicious and fearful townsfolk through your heroic and helpful actions. Among your adventures here, you again encountered the Ogress Baba Yaga, who proved to be helpful this time around, and learnt of your destiny in Mordavia from the gypsies. Rescuing the girl Tanya from the castle lead to a confrontation with your nemesis Ad Avis (now a vampire) and his Dark Master, Katrina, who had teleported you here to help with the summoning of the Dark One, Avoozl and his shadows of darkness. Geased by Katrina, you were forced to gather the summoning rituals and perform them at the altars in the Dark One's Cave.
As the final ritual neared completion, Ad Avis, through malicious treachery, tricked the Dark Master from releasing him from her bondage, and caused her destruction as she tried to save you from his attacks, having fallen in love with you. Because of this supreme sacrifice, her soul was freed and passed on to Hades. After a perilous struggle, you defeated Ad Avis yet again, and banished him to Avoozl's dimension. Erana, who had been trapped in the clutches of darkness since the last summoning attempt centuries ago, banished the Dark One and closed the inter-dimensional portal forever. Her soul too passed into Hades. (These events were the subject of Quest for Glory IV: Shadows of Darkness.)
With the drying up of the swamps and the coronation of the Burgomeister as the
new Borgov of the valley, things gradually returned to normal in Mordavia.
At this point, the Wizard Erasmus, summoned you to Silmaria, a land in grave danger
and in desperate need of a powerful Hero... (to be continued in Quest for Glory 5: Dragon Fire)
