When Taden first came to Lystran, he found evidence that the anomalies were caused by a ship. He sent Maelir to find the ship.
Build a gate stabilizer in Pluma (-1,-3,0) then explore the unknown sectors to the west and find Maelir.
Scan the derelict Astrela, Tserilecx, and Astralecx core, then contact Maelir.
Clear the system of Sortis (-2,-3,1) of Toreisan vessels, call the Astrela and Tserilecx to the system, then contact Maelir.
Stop the Saurum in Raeson (-1,-3,1) from generating the waveform that is distruping the jump system.
Claim the Astralecx Core, then bring the Astrela and Tserilecx within 200k of the Astralecx Core, target it, and merge the ships. Return to Taden in Avar Nidium (-1,-1,0).
