The Pulse-Root Basin is a vast tropical lowland where the environment mimics a living organism. Dark, fleshy trees with pulsing roots filter iron-clogged red waters, while a thick layer of crimson algae traps geothermal heat beneath a shroud of steam. This high-magic zone feels like the interior of a gargantuan beast, requiring travelers to hack through self-healing vegetation. It is a land of vibrant sacrifice and ancient stone ziggurats.
