Princess

The Princess is a town NPC that spawns if all other town NPCs (except Santa and town pets) are present. She only spawns after moonlord has been defeated.

Living preferences
The Princess is unique in that she does not have any special biome and neighbor preferences. She loves up to three NPCs that live nearby. She is also liked by everyone and doesn't receive bad modifiers from having a lot of friendly NPCs around her and have her prices maxed to 150% if there are less than 2 NPCs within 120 tiles.

Trivia

 * The Princess has a unique death message along with the Angler, in which instead of " was slain..." the message reads " has left!" This likely implies that she is a child, further supported by her short size.
