A dryad, 500 years old, from the game Terraria. She comes after you first defeated your first boss. To make her come, just build her a new suitable-for-living house. She's useful in some cases: 1.) She can help you turn corruption/hallow into green. 2.) You can also buy acorns to plant trees. 3.) You can buy seeds for decoration or to help you prevent the spread of corruption.

P.S. Sorry that I misspelled 'Modest'. It had two D's instead of one. And also, this is a modest version of Terraria's dryad. Unfortunately, it's an immodest version. Just avoid the immodesty whenever you're playing Terraria.
