Lilyveil is an environment designed for the game design project Lilyveil. 

Here is the description from the Lilyveil artbook:

Lilyveil is a lively pond-themed village, bustling with joy and life. It’s inhabited by many pond dwelling creatures, such as snails, frogs, dragonflies and more, and the residents are always kind and welcoming! Lilyveil is the place Gil and Eaban grew up, a place full of happy memories.
