Right, you read it correctly. For those who didn't know and haven't guessed what objectophilia is, here is an excerpt from wikipedia on the matter:
I don't think I have to explain the prompt any further. Do your best/worst/weirdest
Oh boy.
First, we'll go with anti-HERO MC to be badass.
Genre is fantasy.
And, because you said harem and not reverse harem, MC is a dude.
we now need to think about how many members in his harem. 10 is too much. 2 is very few. 5 women. That's it.
5 women who are objectophiles. I can work with that.
Plot:
MC is born in a war-trodden land where heroes are chosen through battle. The winners are blessed by the Gods and given gifted abilities as well as spells. Each hero leads a battalion and normal soldiers do all they can to protect the heroes in battle.
Heroes have the ability to use magic that is different from the normal spells that most people can use. The magic is usually explosive, showey, and large-scale.
However, our MC is the opposite. He can only cast spells that will slowly corrode his opponents over time, time that can be a few days to up to millennia depending on the target's mental strength.
During battle, soldiers don't have that much time. His power is dismissed, and the guy eventually gets killed in a battle with another kingdom.
Upon death, his last consciousness spreads his life force through thousands of miles, and casts the [Mind Corrode] spell to hundreds of people.
After thousands of years, the effects of [Mind Corrode] finally shows its true colors: the corruption can pass from generation to generation, and when successful, the corrupted specimen becomes a host for the corruptor.
But our MC is dead, so a Different effect starts to happen.
The corrupted person's mind will only have one goal — to revive the MC.
Eventually, this goal can evolve into "be sane just so that you can fulfill the goal effectively."
of course, the countries have noticed and tried to stop it. They'd even tried to find cures. No one had been successful in fending off [Mind Corrode].
The effects get worser every day and every generation.
The first generation only has 10% of their mind corrupted by the end of their normal lifespans but the second starts out life with a 5% corruption.
the people who have been corrupted do not come and confess in fear that the government shall castrate or infibulate them. The curse withers on.
The Gods decide to interfere and take the Mc's soul out of the cycle of reincarnation and send him off to another world, different from the one where his soul originated from. This cuts off the Fate Energy that [Mind Corrode] was relying on, dispersing the effects.
A few millennia pass.
the MC has lived countless lives in the new world. However, he's slowly starting to remember who he originally was.it was when he got reincarnated into a dragon — he re!embedded a bit.
due to a dragon's nature, this angered him.
he started to devise a plan to get revenge at the Gods for cursing him with that ability.
MC goes ahead and learns magic to place himself into inanimate objects.
of course, he goes and makes thousands of races subservient using his dragon's a bilities.
before he does another 2 millennia later, he assigns the most trustworthy of families to devote their daughters to taking care of"him". MC was lustful.
the objects are important because they will be used to revive him.
over endless generations of daughters taking care of the inanimate objects, the women start to become... Sexually attracted to them.
thus, MC got a huge harem.
but he can choose only five....
basically, that's the first of it. Don't mind me not writing any more. I'll let anyone who wishes to take this over to continue MC legacy.
I would have continued if it werent 1 am and I needed to sleep.
