I don't have enough information to say exactly who Tara Reade is in these stories. She could be an ordinary person with an interesting story, or she might be a public figure in a specific community.
It's likely not a true story. Most of the time, such tales are made up to engage the audience and spark their imagination. There's no concrete evidence to suggest it's based on real events.
Tara Technologies was a 3D cartoon style strategy game. The game was set on Mars in the future. Players could build their own chariots and destroy enemies to obtain resources. There were many achievements in the game that needed to be completed to unlock, such as defeating Big Tony, destroying the enemy's vehicle from 100 meters away, and reaching land at a speed of more than 200 miles per hour. In addition, the game also supported multiple modes and online games. Tara Tech was produced by the British development team, Payload. It was available on PC and XboxOne, and was expected to be available on the PlayStation 4 on August 14th.
One common theme is the struggle between good and evil. Since Tara is often portrayed as a good character in the Buffyverse and vampires are typically associated with evil, the fanfictions often explore how Tara deals with the vampire elements, whether it's fighting them or trying to understand them.
Definitely not. Mara is a work of fiction. It doesn't draw from any true events or real people. The story was crafted from scratch to entertain and engage the audience.
There are some fanfictions that might explore such a scenario. However, it depends on different authors' creativity and the specific plotlines they develop. Some fanfic writers might be interested in exploring the relationship between Mara Jade and Luke Skywalker in such a context, but it's not a mainstream or canon storyline in the official Star Wars universe.
