Over on G+ we do a little magic every Friday called FridayFiveMinuteMap where we attempt to draw a map in just five minutes. Occasionally we have a theme when someone reminds me...I am terrible at this. This week I threw down the theme of Prisons and waited until almost the last minute to draw mine.
Below is the actual drawing with a Critical hit! (see +BareBones RPG )
I liked the map enough I wanted to tweak it a little and present it here for those who might want to use it. All told the drawing took just under five minutes, then another fifteen or so to hatch and detail the image, maybe ten more to tweak in +GIMP and +Inkscape. Below is the clean, white version for dropping into your favorite VTT or in a PDF if you choose to make something cool using it.
I drew this map using Sharpie Pens, on plain white copy paper. I make the map available here for personal use. If you write an alternate adventure or use the map in your game, on your blog, or what have you, please let me know. I would love to know! You cannot use it in any commercial or non-commercial product without my prior approval.
