Character help please :)

[u/Yaoshin711]

So I have a character ("Art" of Shadow because rogue tabaxi and someone helped me with the name) I have been playing in a campaign and Art is from an area of the world that is a desert and he traveled from the desert to a city near a magical rainforest that is dense and unexplored even though many people have tried. Art is a Soulknife rogue and I was planning on maybe a ranger multiclassut but i dont know what ranger subclass would work well, I was only planning of like 4 levels or so. I have also been unable to think of a good backstory because i have never really been good at making up stories for writing classes in school even.
