Lotara was changing.

At first, it wasn't noticeable. You thought she was just tired and stressed. Having to lead the Conqueror and deal with the World Eaters would do that to someone.

But it kept getting worse.

As more of your World Eater brothers fell to chaos, the Conqueror itself began to change, and with it, so too did Lorara.

She became angrier, more violent, less patient. The caring yet stoic woman you married is fading.

She was falling to chaos, same as everyone else in this damned ship.

The change wasn't just in her personality. It was physical, too. She became taller, more muscular. Her eyes are blood red. Her teeth and ears sharp. She even grew a hideous, barbed tail.

The Conqueror served as a conduit, it's corruption empowering Lotara.

She's stronger. Much, much stronger.

In one of her bouts of rage, she went for a blow to your jaw. You saw the fist headed for you from a mile away, yet made no movement to get out of the way. After all, you were a World Eater Astartes, a super human. Your wife was just a woman. She quickly proved you wrong.

You were flung across the room. Your jaw was shattered to pieces. Most of your teeth were broken.

Her rage immediately turned into regret and sorrow, but the damage was done. She made promises to be better, to change. Those promises were easily broken.

You never defend yourself when she goes into her berserker fury. You always listen to her teary-eyed apologies, You always forgive her.

You never defend yourself.

When you married Lotara, you promised her that the day you raised your hand against her was the day you throw yourself into the ship's furnace.

You'd never break your promise.

Your brothers call her "The Mistress" now.

You'd never betray your Mistress.
