What is it?Edit
The greenhouse, as the name suggests, is a greenhouse. It's located just beside the inn and made of metal and plastic glass panels. It's been built by Zwei and is the primary source of fresh vegetable and fruit produce for the inn.
Anyone is welcome to stay and relax at the greenhouse. While there are no real rooms there, parts of it can be separated with curtains and there is some basic furniture available. Plus, everyone is welcome to relax among the plants.
Zwei maintains a storage of gardener supplies: tools, fertilizers, anything, really, in the greenhouse. He happily shares it with others.
