Starts with abuse and/or neglect with either his parents or the Dursley's

Doesn't know his name when Tom finds him

Joined Voldemort's side and gave an unbreakable oath to never betray

His last name is hidden from all except the dark lord or those you choose to know

Loyal to dark lord above all others

Trained to be powerful

Finds a male lover and spends time with him when he is free but cannot have him

May be dark, light, or neutral character for his lover

Tom's reaction is up to you but I would say not happy or that he may try to kill the lover or have Harry do so

This only thing Harry will not do for the dark lord nor allow anyone else to do

Lover may still die totally up to you but Harry will fight for him

Can change Harry's name if you wish

Can be long or short though I do hope for a chaptered fic
