I was going to put your means of propulsion next on my list, but a thought occurred that no matter how fast you travel between recipients, you have about a billion to deliver to in a 24 hour period. This means less than a ten thousandth of a second per recipient, to include travel time, entering dwelling, reading letters, consuming offerings, and leaving gifts. Your physique does not suggest the running speed this would require, and I am sure you make each delivery in person, and do not resort to stooges.
I have to conclude you are somehow distorting space and time to allow this, and would therefore like to request the device that makes this possible. Obviously this is for academic interest, and would not be abused to bypass deadlines or for cheap tricks.
