When you finally have a TL ship and 30 million credits jump/fly to Argon Prime with your TL ship. In Argon Prime dock at the shipyard and buy an Argon Trade Dock. You need to deliver the Argon Trade Dock to the shipyard in Kingdom End.

Once you have docked in Kingdom End, you will be sent another message.

You will be told that you must gather some more resources to complete the headquarters, which includes:
30 x Quantum tubes
20 x Microchips
15 x Nividium

The Quantum tubes and the Microchips can be brought from local stations; however the “Nividium” must be mined from an asteroid. You should store each resource on your TL.

To mine "Nividium" you will need a ship capable of fitting a Mobile Drilling System, can handle XL cargo and a Ore collector. My suggestion is to head to Rolk’s Fate and mine one of the asteroids that you scanned earlier in the Bala Gi Missions.

Once you have found an asteroid containing "Nividium", shoot it once with your Mobile Drilling System. The asteroid should break into medium size pieces; however these medium pieces are still too large. You will need to split them again into smaller pieces by shooting them again with a normal laser. The medium size pieces should split up into small pieces which your Ore collector should be able to collect. Target each "Small" piece and to see if it’s collectable by pressing "I". If it says yes, then press "O" (to lower shields and open cargo bay) and slowly drive into the small piece. Once close enough, your onboard computer should say “Cargo bay now contains Nividium”. Collect in total 15 units of "Nividium" and place on your TL.
