Well i would supply correct coordinates, but l2 is down for the update.
but there are 2 quick shortcuts for two towns.
1. Dark-elf to light-elf crossing. vise-versa.
2. light-elf to oren town. vise-versa. (beware of enemies, too close and they will aggro.)
both crossing involve crossing the mountains, thus saving wlaking time
RED=crossing start points
BLUE=Path
