The Decentral Nature Study is a book (scrap note) that shows a specimen of plants, rocks, and inhabitants in Decentraland.
The Neo-@nimist wandered in this early concept of a virtual planet and encouraged themselves to study the mediated texture and environments. There is no book exploring other metaverses except Decentraland, and WACA is in search of possible series of books.
It is the most well-preserved artefacts that WACA has discovered.
