Introduction: Scarlet Hastur, an ancient horror from the New World, has turned his gaze upon the civilization ladder.

He sent a mental seed into the civilization ladder, giving rise to a malformed, twisted civilization.

But a player of the civilization ladder thwarted all his plans, not only destroying this civilization but even killing the powerful creature hosting Hastur's mental seed.

However, Hastur's mental seed has discovered an even better host, one whose potential astonishes even him.

But the intended host's consciousness is also resisting fiercely. Hastur's mental seed is now at the most critical stage of its parasitic takeover.

Once the takeover is complete, the host's consciousness will be utterly submerged, and this body will become Hastur's incarnation within the civilization ladder.

② Rescue Hogg before Scarlet Hastur completes his parasitic takeover / Eliminate Hogg, who is hosting Scarlet Hastur.

③ Completely eliminate all remnants of Scarlet Hastur's mental seed.

① Civilization ladder weight +2
