I am expecting a major combat the next time I GM 7th Sea. Most of the time, I don't bother with maps. But given potential NPC shenanigans (both pro & anti PC), plus the environment (mountains of Castille/cavern) itself PLUS the MacGuffin threat that may unite the sides (a Fire Mountain), I need to keep track of where everyone will be.
My drawing skills SUCK, however. And I probably wouldn't be able to get a backdrop/terrain in time.
Any advice?
