I'm filthy rich and don't know what to do with it all. Perhaps some tomb and manor runs?

Long story short, I recently acquired a shitload of free Realm Gold.

Long story long, I have been playing RotMG through Kongregate for about a month. To buy Realm Gold through Kongregate, you use Kreds (their currency), and there are a number of ways to buy kreds. I linked my Gamestop card and cashed in some points, I signed up for a 1month trial of Netflix (I plan to cancel penalty-free before it expires), and I applied for a Discover card which I have since cancelled. All of this gained me over 1000 kreds, enough for nearly 10,000 Realm Gold. And I haven't spent a dime of real money.

I don't even know what to do with it all. I now have 4 character slots and 10 vault chests. I have a few characters dyed and colored. I have a pet. Bought some firecrackers and rum. I still have about 5,000 gold left and I don't even know what to do with it all. I'm still a noob working on getting to 2/8, just got my warrior to 1/8. I have no need for a 5th char slot or an 11th chest.

I'm thinking of buying some keys to a tomb of ancients, or water world, or manor. I have no clue. Could we run this as donations though? I don't even know how this works or how to set it up. I'll buy us a tunnel-rat set of keys, and if you could spare a def pot or something I'd be very grateful. Let me know.
