I need to know your goals.
I would do this...
Get a cave. A large cave. A very geologically stable cave. Pay some dwarves to reinforce the cave. Get a big pair of doors. Seal that cave.
Go inside. Start writing things on the walls. Hire a Bard. Have him write a huge epic that results in peace and prosperity for the surrounding area and the reason for it is you. Relate how you (the hero) come across the artifacts of power, how the trials are harsh but for some reason events always unfold for your benefit. Make the bard write it as some sort prophetic story. Feel free to encourage him to write himself into it as the prophet who wrote it. Have him outline how he then wandered off to have a life that was happy and long.
Then make him include that he (the prophet) immediately forgets that he wrote any of this. Tell him it's for his own safety. Then go over it one more time, then wish the following:
I wish that starting one minute after I complete this wish, As far as I understand the terms wish, one, minute, and complete, that the prophecy on the walls would start to come true, as far as I understand the terms prophecy, walls, and true, and be fufilled in a manner that causes the least amount of disruption and loss possible, as far as I understand the terms fufilled, disruption and loss, while proceeding in a fashion that is slow and sensible so as to assure that this area will know peace and prosperity for a thousand years to come, as far as I understand the terms slow, sensible, area, peace, prosperity and years, so that me and my decendents will be this lands protectors for generations to come, as far as I understand the terms me decendents, land's protectors, and generations.
Then the bard forgets his part in any of this and goes off to live a happy life somewhere else. You seal the cave, then enjoy a thousand years of good luck and prosperity.
