So I'm going to try and explain some of what's actually going on here, from the knowledge you have and what your enterprising cast might guess. These guesses are going to come from Amanda and Vega as at the moment the rest of the group is a Schrodinger until the vote is over. You have three options here. Two of them you've seen before, so you have a pretty good idea of what they'll involve. Experience, however, is new, so there's only guesses there.
I talked with my betas today and they pointed out that there was a general lack of information on what the choices might represent, which might be choking discussion or voting. It's my hope that this may help fix that.
Witness
Amanda chose this path at the Tomb of the Zlathbu, and found within the towers of the Shiplord enclave a shard of the world that had once existed before it was ended by the Shiplords. A member of the Hearthguard, the Shiplord organisation who maintain these systems, provided a recorded explanation of what occurred in the star system. How the Shiplords found the race, and how they eventually killed them. Once that was complete, the chamber would provide access to an extensive repository of documentation and other recordings focused on specific points within the history of Shiplord interaction with the Zlathbu. Expect a similar base recording and repository here.
Amanda: It's reasonable to assume that this will be much the same as before, though I'd suspect that the base recording will take place on a more strategic scale. From our vision, the Shiplords were not present in this star system when the Uninvolved acted, and therefore may not know what actually took place.
Suggested support: Technical expertise was of considerable use in the last Tower, as the Witness recordings contained highly detailed sub recordings seeded into the main repository data. Unison Platforms are capable of detecting these now.
Remember
Vega travelled to this section of the Zlathbu's enclave, whilst Amanda remained within the Witnessing Tower to examine deeper records and support other members of her Heartcircle. Remembrance in this case took the form of a quasi-formal ceremony, recognising that which was lost, and attempting to take responsibility for the mistakes that led there. It's a solemn thing, and deeply personal to the Shiplords who undertake it from everything the Harmonial could glean. It also provides a possible viewport into the feelings of current Shiplord culture where the events enshrined in the enclaved are concerned. Vega talked with more than one Shiplord about it, and gleaned a great deal.
Vega: This path is one of emotions, and one that I believe the Shiplords would find most terrifying for us to know of. This is their heart, unshaded by the layers of control that we're used to seeing from them, and I do not know if that visceral pain would be good for any of us. At the same time, though...there is a power in sharing the pain of a witnessed horror. As ways to heal go, it's a very risky one, but we've done crazier things.
Suggested support: The ability to remain calm in the face of this experience will be paramount, and may require specifically tailored support.
Experience
You've only got guesses for what this one might mean, but some of the complex meanings from the translation software imply that this means more than the word. The Shiplords lack any sort of ability to access racial memories like the Marionettes do, but something similar seems to be implied. Maybe a simulation, maybe something more visceral. It's difficult to be sure, given the lack of data, but that it's presented as its own option means it must be distinct from the others.
Amanda: Something new implies importance, perhaps something unique to this system alone. I'd like to see this, but is it the right first choice? I'm not sure.
