To give a summary of the communication attempts:
The Isanamo communication attempt:
Capsuleers involved: Jandice Ymladris & Stig Elendil
We used a wide variety of objects in an attempt to get their attention, often jettisoning them in the hopes of a Drifter response. Science teams aboard our ships kept close track of any possible oddity.
The items used were:
Unknown Sequence
Capsuleer corpses
Corrupted Trinary Relics
Ancient Coordinates Database
Neural Network Analyzers
Sleeper Data Libraries
Antitykhera Element
Redoubt Element
Takhmal Relic Holy Statue
Thukker Loot
The items were flown in one by one with no response form the Drifters, not even when we carried capsuleer corpses. Combination of the items did not provoke a response either.
The only thing that occurred was their ever vigilant scanning and even that was not out the ordinary, no special focus or negligence.
The Evuldgenzo attempt
Capsuleers Uhnboy Ghost & Stig Elendil attempted communication once again at this encounter. Uuhnboy Ghost tried to provoke a response by buzzing various Drifter ships, allowing him to inspect them very closely.
Meanwhile, Stig Elendil attempted light-based communications hailing various ships.
Sadly neither got any response from the Drifters.
Considering Drifter activity in the past, ARC proceeded to remove them forcibly from known space.
You can read about the 3 Drifter encounters here:
Multiple Drifter fleets sighted on a single day!
Do note that the first fleet was destroyed by an unrelated capsuleer fleet & no attempts at communication nor research could be done.
The two subsequent sightings saw the communication attempts before the forced removal of the Drifters.
As noted above, salvaging the Drifter wrecks yielded a previous undiscovered artifact, the Corrupted Trinary Vault, containing the mysterious footage linked above.
To this day, we do not know what drives the Drifters to appear in damaged fleets in our space, nor who did this to them. But until we can communicate with the Drifters, we cannot take chances sadly, as they are simply too powerful to let them roam unopposed in such numbers.
