[Farming] + [Infrastructure] + [Revolution] + [Lord-like] + [A world with a little bit of everything] + [Genderbending]
Tens of thousands of years ago, the undead vanished completely from the material plane during the War of Purification.
Viola transmigrates here, only to discover that her class is... Undead High Priestess?! All she has to do is increase the number of her followers.
But not long after she arrives, her family is wiped out in a political maelstrom, and she becomes a wanted criminal in the United Empire.
Her flight from place to place exposes her to countless people struggling to survive. Officials levy exorbitant taxes, nobles oppress the common folk, and she resolves to change it all. She'll make them her followers!
At 10 followers, she summons a powerful undead lord from the Realm of the Dead.
At 100 followers, she can mass-promote them to dark knights and beat the kingdom's holy knights to a pulp.
The druid is dumbfounded:
“How does this Undead High Priestess know more about farming than the Goddess of Harvest?!”
The elven elder says, “For the undead to touch the Tree of Life is sacrilege... Wait, what do you mean the Tree of Life is sending them energy?”
When the Inquisition of the Temple of Holy Light lays siege to the city, the people behind Viola all turn around at once: orcs carrying hoes, dwarves holding blueprints, and a sea of skeletons operating harvesters.
“Just a friendly reminder,” she says with a smile as she ignites the flames of revolution.
“This missionary's construction crew specializes in tearing down the old world's load-bearing walls!”
