I think usually if it can be in a forest, then I am well within my literary rights to write it in. Preferably not always popping up with stuff that happens to be there to save my ass.  

Like in my linked fight with Aeryn. That was a challenging map with its own tricks(mainly height, intensified sunlight), that we played with. Varying thickness with the glass, and how fragile they were, without getting carried away. 

I probably could have won if not for.... him.
