Princess

The Princess is an NPC vendor that will spawn once the following conditions have been met:
 * There is an empty house.
 * All other town NPCs (not including Santa Claus or town pets) are present, meaning that she will only spawn after defeating Plantera.

Living preferences
The Princess is unique in that she does not have any biome or neighbor preferences. She loves up to three NPCs that live nearby, as well as being liked by NPCs around her, incurring no bad modifiers for crowding. She also hates being lonely and her unhappiness is maxed to 150% if she isn't surrounded by at least 2 other NPCs within 50 tiles, or 2 other NPCs within 240 tiles but farther than 50 tiles.
