Many years ago, while living in Silmaria, she assumed name of the Dark Master, trained a young magician, Ad Avis, in the ways of dark magic as well. He hated women, and this amused her. She gave him "Life Eternal after Death", the mark of the Vampire, but did not kill him. Ad Avis fled from her to Shapeir, hoping to gain enough power that he would never die and have to serve Katrina.
Long ago, she traveled to Mordavia, because she heard rumors of the Cult of the Dark One. Seen as a stranger, she moved into the castle. The stranger was only known by the ominous title, 'the Dark Master', and there were rumors of Vampires. However no one met the stranger (neither knowing she was male or female), and as no one was ever killed by the Vampires, gradually the talk faded. She spent many decades living in the Land of Mordavia. She began to think of herself as the local ruler and liege Lord.
She returned to Castle Borgov in Mordavia five years before the Hero came to Mordavia, believed to be one of the Boyar's cousins. Though she apparently left on a journey and returned one year later. There she was joined by Ad Avis when he was killed by the Hero. Ad Avis was now her Vampire slave, unable to disobey her orders.
Although a Vampire, Katrina was still emotionally a woman. Unable to enter the town because of the protective magic of Erana's Staff, she had her servant, Toby, lure a child, Tanya, to the castle. There Katrina turned Tanya into a Vampire, to be Katrina's young daughter through eternity.
In order to summon Avoozl, Katrina had to find seven rituals which were scattered throughout the land. She found the "Mouth Ritual", but she needed a Hero who could survive the dangers of Mordavia and move freely by day and night. It was Ad Avis who suggested that the Hero would make the perfect pawn. So together they performed a ceremony of summoning to Teleport him to Mordavia.
Unfortunately, the Dark One's Cave distorts all magic in the valley. The hero was summoned, but rather than arriving in the castle surrounded by Katrina and Ad Avis, he arrived in the Dark One's Cave. Katrina quickly changed her plans about forcing him to find the Dark One's missing rituals, and decided to trick him instead. She used the "Mouth Ritual" to open the Dark One's Cave and allowed him to leave.
She and Ad Avis spied on the hero through the crystal ball at night. This caused some of his peculiar dreams when he slept at the Hotel Mordavia. 
Character and traitsEdit
Katrina was the Dark Master, the vampire Wizard. She is a powerful and complex person who refuses to accept weakness in herself or others. She was trying to summon the Dark One, Avoozl, in order to fill the land with eternal darkness, so that she would never lie helpless in her coffin again.
Katrina was a ruthless and deadly killer when she wanted to be, but she left the townspeople alone, partially because they were protected by Erana's Staff. It was also partially because she thought of herself as the ruler of the land, and they as her people. It was the rainstorms she summoned that cut Mordavia off from the rest of the world. She was completely self-centered, and thought nothing of the consequences of summoning Avoozl other than allowing her to travel by day.
Katrina is also a passionate woman who has never known true love. The hero's actions determined how she felt about him. He could become either a despised pawn, or earned her respect and admiration.
Behind the scenesEdit
It is rumored that she was a member of the Wizard's Institute of Technocery many years ago, but left to study the dark arts. Ultimately she was no longer acknowledged or expelled by the Wizard's Institute of Technocery who stopped all contact with her, or she to them (going as far as the darkening of her picture in the institute). Technically the painting in QFG2 is not named (it is referred to as the portrait of "Darkness"), but is most likely a nod toward the Dark Master. In QFG2 the Dark Master is briefly mentioned by Ad Avis near the end of the game.
QFG4 implies that Katrina is pulled into the dark universe where the Dark Ones dwell, trapped there much like Erana previously, and will continue to exist there along with Avoozl for eternity. QFG5 on the other hand says she was killed and went to Hades, from which the player can rescue her.
Katrina wears a violet dress with red sleeves and walks barefoot. In her first appearances, she has a blue hood over her dress.
True Identity Edit
Katrina turns out to be a vampire residing in the Castle abandoned long ago by its previous owners, and is the Dark Master of Ad Avis, the villain of the second game in the series. She manipulates the Hero into finding the various rituals that will bring the Dark One Avoozl back to life. Her goal is to use Avoozl to plunge the world into eternal darkness. Despite her sinister actions, Katrina is depicted as a sympathetic and deeply lonely character; the Hero learns at one point that she has abducted a child from the village, Tanya, because she longs to have a daughter of her own. Katrina becomes furious when the Hero later rescues Tanya Markarov and returns the child to her real parents. During the finale of the game, Katrina realizes that she does have genuine affection for the Hero, and she sacrifices her un-life to save him from an attack by Ad Avis - playing into the hands of the malevolent wizard.
Path to Redemption Edit
In the last game of the series, Dragon Fire, one of the Hero's quests takes him to the Greek Underworld. There, he is given the chance to give up a portion of his life force to bring Katrina or Erana back to life. If revived, Katrina takes up residence on the island of Zante. Although no longer a vampire after her resurrection, Katrina still feels unused to daylight and casts a spell over the island so that anyone who approaches can only do so at night (i.e. if they approach during the day, they arrive after nightfall). Learning that the Dragon of Doom is rising she urges the Hero to flee the islands lest he become just another of its victims. She claims her own enchantments will protect her new home from the Dragon's power and claims at first she has no interest in "playing the hero." Ultimately, however, she assists the Hero in his desperate battle against the Dragon of Doom that is threatening the land of Silmaria (and she causes a great deal of damage to the Dragon, showing how tremendous her magical powers are). Katrina is a potential bride for the Hero in Dragon Fire, and is most suited to a wizard or a warrior (not paladin) character, but the game must be patched before she can be successfully wooed.
