One resource sadly lacking from the roleplaying game (as per this writing)
would be any detailed information on the size of the lands of Azeroth, and travel times to get
from one place to another.
For my own campaign, I've tried to develop some maps and other resources to assist in determining
travel times. These aren't very "pretty," as they're hacked together from screen
captures, with a bit of touch-up work based on various alternative sources. However,
I hope that this might provide a starting point for GMs running broad "overland"
campaigns.
Please note that, out of necessity, I've made a lot of arbitary assumptions, filling in various gaps.
The scale of the maps is based upon a tidbit of information from the
White Wolf Forums, that Kalimdor is approximately 1600 miles
across, east to west, at its widest point. From that piece of information, I've extrapolated the
rest for my maps.
These maps are presented in the hopes of serving as a useful tool for GMs. They are (in their present
form) cobbled together from screen captures from World of Warcraft and the Warcraft RTS games, and I
have drawn heavily from the efforts of many other people. (Among these would be "Warlock", who put
together a comprehensive map of Azeroth
on his Scrolls of Lore web site. I've used his map as a
guideline for the placement of various islands, and for relative sizes of the continents.)
As of this writing, I only have Kalimdor and the Eastern Kingdoms done. The "no labels" alternate
versions are just the background without any of the labels I've added. (They may or may not include
some of the original "zone map" labels in whole or in part. In some places, I erased out the original
labels during the process of "zipping" the zone maps together and creating clear space to add my own
labels.)
