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 beating 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.

Trivia

 * The name Rosetta is likely a reference to the character in the Disney franchise Tinkerbell.
 * Rosetta is also the Japanese name of Rosalina (ロゼッタ) in the Super Mario series.
 * Five of the Princess's names are Japanese, each of which have different meanings.
 * Ai translates to "love" (愛).

 * There is a spelling mistake in one of the Princess' quotes, where she says "the Golfer passion" instead of "the Golfer's passion".
 * The Princess has a Happiness quote for herself: "", which can't be seen in game, as it requires the Princess to have another Princess as a neighbor, which is impossible because two of the same NPCs cannot be alive at the same time in normal playthroughs.
 * The Princess shares the name "Faye" with the Dryad.
