The Heaven's Gate Seige | December (or longer) | Version 2.0 | Explained

[Thyrzul]

I won't pretend I've read all the comments because I've thoroughly visited this thread last night only, bit tired at the time, and in general having better things to do, so I'll just reflect on certain points of the OP and dialogue in that regard.

You've collected information supporting the idea that Satsuma blueprints are on the Arch based on Discovery Wiki articles, implying those articles are openly accessible knowledge inRP. If we accept the implication then this information supports the logic behind Sunny's thoughts quite well, and his well educated guess justifies his decision to take on the Arch, but in reality does not support the notion that he'll 100% succeed at finding the blueprints there, as it does not take into account whatever changes Aoi have done to whatever was left on the base after they took it over from Kusari authorities plenty of inRP years ago. In that regard all of us kind of have to rely on owner faction and dev stance. This also makes responses, like the following, slightly inaccurate:

We have explained how with reason the blueprints need to exist.

Another thing is that Sunny decided to rely on Order and BD because of their successful raid(s) on the station in the past, but that also is not a guarantee that Aoi have left everything internal unchanged, quite the opposite as they very likely restored, upgraded, fortified internal defenses ever since their last defeat against Order and BD. Reliance on these two factions is more or less justified, but on an ooRP level success is not at all guaranteed, not even for a boarding party to reach any data cores for the blueprints, and that also has to be kept in mind.

Lastly, I hope this little oversight in your OP doesn't ruin your plans too much.
