You can place KDs in order of thier standing at the end of the age into islands corisponding to thier rankings from the previous age.
Such that the top 9 KD are all placed on island 1
Ranks 10-18 can be on island 2
and so forth.
This would add a degree of bragging rights. and a degree of honorifics to be the top.
It would also help a bit with scolding someone from "hitting into bigger KD's"
This way there would be no/less surprise that you were hitting into a bigger/better KD as they are on a higher seated island.
