The mist thins, unveiling the harsh, sprawling vistas of Etheria – a world rated SSS in difficulty. You stand on the threshold of a new reality, freshly graduated from the academy of demonic overlords. In your grip, a Tower Seed pulses with latent power; the sacred Tome rests against your side. Beside you, your randomly-assigned high-tier attendant materializes from the gloom. The wind carries the scent of ozone and imminent danger. Your System interface flickers to life, its silent hum a constant presence in your mind.
