Greta's family arrived in the area that would become Danesti generations before her, escaping from the Romans according to her knowledge. Alucard suspects Greta could trace her family lineage back to Carthage. They came to that area back when it was "just a wide spot in the road" and settled it, along with others who would travel from scattered locations seeking a community to call their own. She became the head woman of the town in her time, acting as its leader and commander.

When night creatures began attacking the village seemingly out of nowhere, it was Greta who organized the village's defense and sought to find aid from "The Alucard" in Dracula's castle, which was the nearest location to the village.

When Alucard arrived, Greta made a point of making it clear she wasn't going to let him half-heartedly aid her people, as they were her responsibility and her calling on him fell to her if it went badly. When he affirmed that he was sincere in his offer of aid, Greta decided that Danesti was no longer defensible, and the decision was made to relocate the villagers to Dracula's Castle, which would offer more protection. Along the way, Greta made mention of her ability to sense magic in people and its affiliation as a result of living remotely and closer to nature, and used the opportunity to voice her distrust of Saint Germain, who'd taken up refuge in Danesti recently and traveled with the group. She also made evident her ability to fight, taking out night creatures single-handedly.

Upon arriving at the castle, Greta took to setting up the rest of the villagers. As a settlement was constructed, Greta started going through the castle's pantries, looking for ways to stretch the foodstuffs the villagers brought further, and talked to Alucard about the castle's defense, coming that she hoped the castle doors would keep people away. By nightfall, however, the grounds around the castle were invaded by the vampire Dragan and his armies, following the instructions of Saint Germain in the hope of performing Dracula's resurrection. Greta mounted as much of a defense as possible, which could help to fight the night army, but was forced indoors by the onslaught. Eventually, however, Trevor Belmont and Sypha Belnades were teleported to the castle to aid Alucard, and the three pushed back against the monsters while Greta helped defend her people.

After the armies were defeated and the conspiracy to resurrect Dracula was thwarted by the trio, Greta talked to Alucard and had come to the decision that the Danesti refugees would settle a new village around the castle and the Belmont Hold instead of returning to their old lives.
