Some incomplete info above.
Step 2 - hail random scorpiki until you get (be sure to go through full dialogue or quest breaks):
[Sat Jun 15 10:55:58 2019] A scorpikis says, 'I am proud to speak to one of the great ones. I am an outsider, but I have honor. What can unworthy me do for you? Have you come to punish those that [unjustly exiled] me?'
[Sat Jun 15 10:55:58 2019] Your task 'What Makes a Scorpiki?' has been updated.
[Sat Jun 15 10:56:00 2019] You say, 'unjustly exiled'
[Sat Jun 15 10:56:00 2019] A scorpikis says, 'I was [Manus]. I have been forced away from god only because there was not enough food to bring back. Less fighting above means less food. I cannot make more food fall from the sky.'
[Sat Jun 15 10:56:02 2019] You say, 'Manus'
[Sat Jun 15 10:56:02 2019] A scorpikis says, 'You must know Manus, great one. They guard the lesser temple as our teachings say we should. We are not... They are not the great Aculeus who guard the portal to heaven, but they have purpose. Now I have no purpose. I have no value to the great ones, to god. I should not speak to one such as you. I bring more shame by daring such a thing.' The scorpiki lowers its eyes and goes silent.'
Step 3 - again, go through dialogue after hailing scorps in the NE tunnel:
[Sat Jun 15 10:56:55 2019] You say, 'Hail, a scorpikis scrounger'
[Sat Jun 15 10:56:56 2019] A scorpikis scrounger says, 'Great one! I am your servant. I currently lead the Manus and am here to [serve]. How can we help you, great one? What little we have is yours.'
[Sat Jun 15 10:56:57 2019] Your task 'What Makes a Scorpiki?' has been updated.
[Sat Jun 15 10:57:02 2019] You say, 'serve'
[Sat Jun 15 10:57:02 2019] A scorpikis scrounger says, 'We have kept the temple as required. We do not forget the god that made us. We teach our children the ways. We only wonder why you have [abandoned] us?'
[Sat Jun 15 10:57:05 2019] You say, 'abandoned'
[Sat Jun 15 10:57:05 2019] A scorpikis scrounger says, 'Lifetimes have passed while we guarded the sacred places and you have not come. We worried that we had done something wrong. Was it the foolish [Tarsus] that angered you? Have we angered you? What can we do to please god?'
[Sat Jun 15 10:57:07 2019] You say, 'Tarsus'
[Sat Jun 15 10:57:07 2019] A scorpikis scrounger says, 'They think themselves superior, but we know they falter in their duties. They have shirked their duty. They have allowed unfit to live, unworthy to remain in the temple. It must be them that [have angered] you.'
[Sat Jun 15 10:57:16 2019] You say, 'have angered'
[Sat Jun 15 10:57:16 2019] A scorpikis scrounger says, 'I knew it to be true. This is a relief to us, great one. It will be pleasure to watch god's wrath punish them.' Bows its head in humility, no longer able to speak.'
Step 4 - same deal in SW tunnel - you get:
[Sat Jun 15 11:03:35 2019] You say, 'Hail, a scorpikis'
[Sat Jun 15 11:03:35 2019] A scorpikis looks excited at seeing you. 'Great one! You have come as we have prayed. We have great need of divine [assistance], as you know.'
[Sat Jun 15 11:03:35 2019] Your task 'What Makes a Scorpiki?' has been updated.
[Sat Jun 15 11:03:38 2019] You say, 'assistance'
[Sat Jun 15 11:03:38 2019] A scorpikis says, 'A monstrous child has been born to the exiles and allowed to live. It wanders the land above and hunts any of us that leave to hunt or scavenge. Even the horned ones fear it. Only one of the divine can defeat it. Surely [that is why] you have come.'
[Sat Jun 15 11:03:39 2019] You say, 'that is why'
[Sat Jun 15 11:03:39 2019] A scorpikis says, 'Thank you, great one. I will wait here to honor your success.'
