"Dear friends, we've gathered here today to bear witness to the union of Luni Kat, and Nezu Rat. Despite the difference in their ages and wealth, they have somehow found love among the sea of others. Is there anyone who believes that these two should not be wed? Speak now, or forever hold your peace."
...of course, both Nezu and Luni might've had their reasons to not be wed, but neither was going to be speaking up!
