An Oathstone binds a Shin to whomever holds it and commits him/her to its holder's wishes.
In the Shin culture, those who add are to be revered; great people create food and clothing.. Those who take away - warriors - those who kill - are considered the lowliest of Shin; they are traded and sold between houses, like slaves.
|“||Men trade and sell them between houses by way of little stones that signify ownership, and any man who picks up a weapon must join them and be treated the same.||”|
Some believe these stones to be Oathstones. Whether these are in fact the same, Szeth son-son-Vallano, Truthless of Shinovar, has an Oathstone which is currently being held by Taravangian and he is apparently honor-bound to do anything that the holder of his Oathstone requires of him. This Oathstone is a sphere-sized chunk of rock with a few quartz crystals set into it and a rusty vein on one side.
