During the olden age of the world of Terraria...

There exists a race known as the Dryads. Humanly in form, but nowhere in power. Known for their connection to nature, and green theme with their clothing made of vines/leaves and green hair, they mainly reside in their own natural areas, supposedly dormant until the world comes under threat, for it is their obligation to protect Terraria.

Forests surrounded your local village, and you are aware within those forests, communities of Dryads exist. You've been a bit curious about them, but alas... what of their mystical business is yours?... well, actually, it is now. For one day, you awoke to some Dryads around your simple village.

Some seemed to just be positioned in certain places and looking around, as if awaiting an impending invasion. Meanwhile, while outside, your eyes happened to catch the appearance of one specific Dryad, with a more chiefly appearance, speaking to your town's chief.

Faye: You are lucky your town is close to our presence... and unlucky that it's also within the vicinity of the rapidly land-spreading Corruption AND Crimson. sigh Just let us remain here. We are here to protect all the grounds of Terraria from these infecting evils... muttering since it's not as if you all could... Okay, Mr. Human Chief Sir?

The slighly perplexed chief scratched their head and nodded, before walking away. Faye let out a breathe of air and briefly glanced around... then noticed your look at her.
