I'd like to join, and propose that we remedy the distinct lack of financial instruments being distributed. Specifically, I'd like to establish the following.
1) Lines of Credit for Adventurers - A would be adventurer lacking the funds to finance their endeavor can petition us for money, which we would grant them, with the expectation that the funds be payed back, with a credit establishment surcharge, within an established time frame. This solves the problem of expensive quests being out of reach of the average adventurer. It does create a problem of needing to be able to hold our debtors accountable, so I propose a portion of returns from these credits be set aside for bounties on those who break faith with us. Additionally, should it come to it, we can attempt to establish relationships with other guilds such that we can convince them to sanction the delinquent debtors.
2) Throne Bonds - We can issue bonds to individuals and guilds based off of our ability to buy throne debt and charge interest on it. We would establish the terms of this interest with the throne, and then keep a portion of the interest and distribute the rest to the purchaser of the bond. This has less risk than the above, because the throne is relatively less likely to default on debt.
If these schemes are successful, and we are able to grow substantial funds, we could begin to offer savings accounts with interest based off of allocation into each of these strategies, and only keep enough on hand to pay out portions of the held funds, but that's further down the road. Also, as purchase of property becomes possible we can offer mortgages, and as high risk opportunities become available, i.e. shipping, we can offer insurance.
Also, I'm willing to post day/night phase stuff.
