Zone 2 is the arid plate in the original four-zone concept art and worldgen introduction. Official posts describe dunes and canyon country with their own blocks, furniture set, and creatures.
Scarak hives and Cactees are the names most consistently attached to this plate in studio writing and media. Treat those as peoples and wildlife of the sands — not as a complete spawn list.
Exact ore rates, temple floor counts, and heat-damage numbers are not on a public official datasheet. This atlas stops at climate, named cultures, and what the studio has shown.
