My progress so far:
I landed near the freighter crash site on planet Aputon Sigma. According to the ship's log, the Sentinels destroyed the whole region. Only a Korvax entity, Nada, and a Gek specialist who came to the freighter to investigate, Polo, survived and escaped. I flew to a Holo-Terminus nearby and contacted Null to tell what I had found. Null wanted me to investigate further and talk to cartographers of each species(Gek, Korvax, and Vykeen). I decided to go along with Null's plan. I also found a temperate planet, Boeot XVIII, and built my second base. (log #20)
I decided to go along with Null's plan to speak with cartographers. I met a Vykeen cartographer at the Konaka Stellar Observer station, who told me to prove my worthiness by visiting a Vykeen reliquary on planet Jodice G20. I got an ancient tablet from the reliquary and showed it to the cartographer. In return I was told of Vykeen's history. Before finding the next(Korvax) cartographer to talk, I warped out of Konaka system and reached Rakino X system to check out something called "Atlas Station". It looks like a kind of space station where you can contact Atlas. Atlas gave me the blueprint of "Captured Nanode". I'll visit more Atlas Stations to find out what it's all about. (log #21)
I discovered a settlement on planet Erheg II in Rakino X system. I defended the settlement from Sentinel invasion and became Overseer there. On the way to the 2nd Atlas Station in Gagasera system, I received a distress call from my settlement. So I teleported back and took out another wave of Sentinels. Shortly after that, Tethys from the Space Anomaly station contacted me and told me to check if there is anything left of the Sentinels. I found a damaged Sentinel drone. (log #22)
I visited the Space Anomaly station to meet Tethys. Seeing the Sentinel drone shell I had obtained, Tethys told me to get some components from other Traveler entities in the station. Maybe this drone could be repaired.
I walked around and talked Travelers in the station. Some of them gave me what they had, such as nanite filament, portal phylactery, and beads of glass.
Tethys successfully repaired and revived the drone, and gave me Sentinel Flare to summon it.
I couldn't use the Flare in the Space Anomaly station because Sentinels were not able to warp to this station.
I left the station and went back to my settlement on planet Erheg II. Using the Sentinel Flare, I summoned a blue colored Sentinel drone. It didn't seem to be fully functional, but I could extract a local coordinate.
I flew to the location according to the coordinate. There was a huge towering structure, guarded by multiple Sentinels.
It's a Sentinel Pillar.
Considering that I was playing permadeath mode, I decided to retreat for now and get back to the Space Anomaly station. Before taking on the Sentinel guards, it would be better to obtain a cloaking device which would make me temporarily invisible.
I got back to the Space Anomaly station, visited multi-tool upgrade terminal, purchased the blue print of cloaking device for my multi-tool, and built one.
With cloaking device installed and ready to use, I returned to the Sentinel tower.
I activated cloaking and approached the tower. There was a terminal nearby. I tried to sneak up and access the terminal, but it was locked by 3 control nodes connected to the tower. No choice but to fight.
I destroyed the control nodes, and also sentinel guards along with them. Cloaking device was quite useful when running away and recharge my weapons.
From the terminal, I obtained a few blueprints. They were for Exocraft Summoning Station, Minotaur Geobay, and Sentinel Hardframe Right Arm.
Additionally, my drone gained the ability to speak properly.
The drone suggested me to build a Minotaur mech and upgrade it to Sentinel Hardframe Mech. Now that I got a blueprint for right arm, I would need to get blueprints for other parts. But first, I'm going to build the Minotaur mech.
