A piece of magically documented paper that gives the holder the right to a share of Oswos Trading Company, including an allocated percentage of its revenue annually. The document also is a evidence of ones membership and might grant one such shareholder certain befits when dealing with the company's many partners and subsidiaries, be it trough favours or by discounts on company goods.
The paper is also magically linked by blood to its owner, allowing for ease of identification in case of theft and ensures the documents validity. A shareholder also gains their own account in the Host Ori-gan banks(unless they already own one) allowing for ease of transactions between continents and countries, or for buying more expensive items and properties where a waggon full of gold and silver simply would make such sums require more labour than they would be worth.
