Return the map! It will bring you great danger.
The map is not the story, but if your characters leave the house and wander around at all, you'll need a map. You can have it before you begin, or you can draw it as you go, but you need a sense of location or you'll get lost, and no one likes it when the author -- the tour guide, after all -- can't find their way around.
My maps are minimal. High Fantasy has a history of being extravagant with unnecessary details, and I resist that -- I tend to follow the maxim "Cut out all the parts that aren't interesting" (Ray Vukcevich, to Jay Lake, as related here)
So, yes, I have my maps. Right by my computer so I can see where the action is happening and where my people are going. Check that it all makes sense.
Still, somehow, it didn't occur to me that the reader might also like to know where the action was happening and where the characters were going. So I was surprised when my editor said, "we'll need your map, of course."
Need my map? But... but... I'm not a map person. I just have these sketches...
No problem, my editor says, we have a guy for that.
I do a little research on their guy and I'm suitably impressed; he's discussed with reverence and awe. His job is to take my map and make it look good. I provide the raw materials and he makes it sparkle and shine.
I slowly exhale. I don't have to worry about the map after all.
Well, wait -- I have to give him something, and it has to be correct. I take a closer look at the sketch I'm planning to send him, and I realize some of the details are, ahem, not quite right.
Oh, not the book -- the narrative itself is flawless, as to places and directions. Ahem. But primarily it's my map that needs fixing. Provinces where they should be. Villages and cities moved to the right -- if general -- location. Major rivers inserted. Show the Great Road. Things that if you're going to bother with a map at all, need to be present and correct enough to elucidate rather than befuddle.
Here we go into the warm part of the year. The well-lit part of the year. Good light by which to draw.
