Hi all, I am planning on including a potential love interest in my upcoming fiction, here on RoyalRoad.  The girl in question is an immortal, she was turned immortal at a young age (precise age to be determined, but hoping for somewhere in the range 13-16 TBD) and as such is stuck with a pre-teen body.  Her actual age is now between 18-22 also TBD and her mental/emotional age probably even further than that, on account of all the shit she's been through in her life already.

So a lot of of what I'm wanting to do with this story is gonna depend on what my options are, without running afoul of the admins.

Will this run up against the pedophilia rules, and if so, can I get away with it if I handle the sexual aspects of the relationship with a lighter hand?

as long as there is no explicit description i think you will be fine. just decribe her as looking younger than her actual age and be vague about it. do be sure to tag correctly though when making your story. (specific tag for sexual content.)
