Ryo Silverbrow

The Harbor
If you try to talk to him, he will reply:
 * Ryo Silverbrow: Welcome! I am in the service of the Coin Lords, specializing in extra-dimensional magics.
 * Ryo Silverbrow: If you are in good favor with the Coin Lords, bring me a Collapsed Portable Hole and I can correct the enchantments on it.
 * Ryo Silverbrow: If you don't have a Collapsed Portable Hole, I can still help you in exchange for some Astral Shards.
 * Ryo Silverbrow: That will give you more inventory space.
 * You: How much will this cost me?
 * You don't have 150 Coin Lords favor
 * Ryo Silverbrow: Before we speak about that, you must get Montague Goudreau's approval.
 * Ryo Silverbrow: You can find him in the Marketplace, next to the Lordsmarch Bank.
 * 
 *  (You have 150 Coin Lords favor and have spoken to Montague Goudreau)
 * Ryo Silverbrow: My prices are quite reasonable, and I can forgo the normal cost for 6 Astral Shards.
 * You: Give Astral Shards (This will increase total inventory by 20 spaces.)
 * You: Give one Collapsed Portable hole and 100,000gp (This will increase total inventory by 20 spaces.)
 * You don't have the currency or the portable hole
 * Ryo Silverbrow: I can only upgrade your inventory space if you bring me a Collapsed Portable Hole.
 * Ryo Silverbrow: All finished! Enjoy your new space.
 * You already bought the extra space from him
 * Ryo Silverbrow: You have already upgraded your inventory space! I can do no more for you.
 * You: Sorry for wasting your time.
