The map I am working on is huge and it is a whole world map... I am trying to set markers on the map as to where locations are but I cannot decide how many markers I need.

For example,
I have 14 thrones in this world, after a big event 4 were lost and now there are only 10.
I am going to put markers on the 10 Royal Cities and the 4 Ruins.

What other markers should I include?


thanks
