The letters are complied and mailed to all of the heralds on the commenting list. The commenting heralds have a few weeks to think about and research the submissions on the letter. Eastern Crown collects all of the comments and puts them in a file for that particular letter. He will consider all of the comments and make decisions on the submissions. It actually does happen.
Positive comments are really nice.
You will receive a letter from Eastern Crown stating the problem with your submission. It could be a conflict or part of your name doesn't make sense. If your submission is returned, you have one year to resubmit free of charge. At this point, you should be working with your local herald to see what you can do to make it pass. The process that happened at Kingdom level with Eastern Crown is now repeated at an InterKingdom level.
