Groth Island is located in the waters surrounding Hethereau, a sizable island exploration zone. In stark contrast to the urban landscape of the city, Groth Island preserves a largely untouched natural environment — dense woodlands, open wilderness, hidden caves, and rugged coastlines form the primary terrain. The island is sparsely populated, with only a handful of temporary research outposts and abandoned structures scattered across it.
Groth Island draws the Appraiser's attention because it is a hotspot for anomalous phenomena. Oddities frequently appear across the island, and Encroachment events occur periodically, causing unnatural changes to the local environment. The Bureau of Anomaly Control has classified Groth Island as a priority monitoring zone, regularly dispatching personnel for inspections and data collection.
When exploring Groth Island, the Appraiser must respond to various unexpected anomalous situations while collecting valuable materials and clues scattered throughout the island. Different areas of the island feature varying danger levels and environmental characteristics, requiring players to formulate sound exploration strategies based on team composition and mission requirements. The secrets of Groth Island run far deeper than what meets the eye, waiting for courageous and capable Appraisers to uncover them.
