story plans

hey guys im just going to go straight to the point

im tempted to start writing about a vigilante style punisher who wears a mask (dont have any ideas for the mask) who could also change his appearance due to illusion spells that hide his identity who runs into rarity by mistake on one of his protection missions
AKA prince blue blood who has signed a sort of contract with blue blood who hides his identity of course the guy whos the main character really just kills whoever he feels like it but hides behind the whole vigilante thing

of course im up for ideas and this may not start till july so i coud do with some ideas
