There are various 'Star Wars Ahsoka lesbian fanfiction' out there. Some might focus on an alternate universe where Ahsoka has a relationship with another female character. For example, there could be a story where she forms a deep bond with a female Jedi from a different order. It often involves exploring the characters' emotions and how their relationship develops within the Star Wars universe, with elements of adventure and the Force.
In the Star Wars universe, such a scenario would be highly complex and out of the ordinary. Ahsoka has a deep connection with the Jedi teachings, and Darth Vader is on the dark side. If she were pregnant, it would likely be a situation full of moral and ethical dilemmas. She might struggle with protecting the child from the Sith and Vader's influence, and also deal with how the Jedi Order would react, as they have strict rules about relationships and attachments.
Her opponents could be the Separatist forces. Umbara was a planet involved in the Clone Wars, so it's likely that battle droids and their commanders would be her foes. They would be trying to gain control of Umbara's resources or strategic locations.
In some versions, it could be a former ally who has been corrupted. This character, once on Ahsoka's side, has now turned against her due to some external influence or personal greed. Their knowledge of Ahsoka's strengths and weaknesses would make them a formidable opponent, and they could be the one to cause her death.
