I have 2 idea’s that may be worth trying.
1: A werewolf story where the main character is bitten and has to hide his curse from the world and not kill anyone or else risked being hunted by a group of monster slayers of which he is also a part of.
2. A fantasy story of a war, except this war literally plays out like a real war,
With hundreds of small skirmishes leading to many battles to try and take over land.
For some reason these are actually pretty original so I want to try one of them out.
(Also know I will have to do a fair bit of research for option 2)
