hmm what type of fantasy world do you want? So many options for that.... *brain is swimming with ideas*
and do you want to be like mercenaries?
I mean if one of us is hunting the other, then we would really just need to come up with the reason why one of us is chasing the other. Like Races would do it... One could be a 'monster' (term used lightly), Or it be something else... Like the 'assassin' could be taking out one of us for their boss, because they would know something they are not suppose to know.
Details are to be worked out once I know what you would like to do~
Also would you like this to turn into a romance OR partnership OR something else. We should have a ending in mind, so we know where we are going with the story. (can be general)
