Information
The East Reach has a number of unique customs and proverbs exotic to areas of Allraan such as New Nevaeh. There is a strong bathhouse culture there, with bathhouses made especially for children. Other customs include travelers buying lanterns marked with the name of their destination and the use of magic fireworks that light up the sky akin to flowers made of incandescent colors. It is said that sharpening swords forged in the East Reach requires a special whetstone.
"If you're given a gourd, fortune's your reward!" was apparently an East Reach proverb according to Iugo.
