How to unlock the engineer Marco Qwent in the Sirius system. First of all you need a system permit for the Sirius system which can be had by completing missions in the Procyon system.

Make yourself allied with the local factions and you will eventually get a Sirius system permit invite mission.

Once you have the permit, you will need to unlock ELVIRA MARTUUK. Once you are Grade 3 with her, you will receive an invite to Marco Qwent.

ELVIRA MARTUUK


Below is the criteria you need to meet to gain access to ELVIRA MARTUUK

MEETING REQUIREMENTS
Attain a maximum distance from your career start location of at least 300 light years.

UNLOCK REQUIREMENTS
Provide 3 units of Soontill Relics.

Soontill Relics


These relics can be found in the NGURII system, in the Cheranovsky City. Head over there buy 3 of them then head over to ELVIRA MARTUUK and hand them in.

Grade 3 Level Access


This is really simple. All you need to do is keep hammering the grade one upgrades until you hit 40% grade 3.

MODULAR TERMINALS


Mission Rewards : LHS 2260, LP 499-49, 64 ARIETIS.

Now that you have unlocked ELVIRA MARTUUK and gained Grade 3 level access with her, we need to head over to the Sirius system and run some missions until we get an invite to Marco Qwents base. Once we have done that, you will need to source 25 Modular Terminals.

This is the difficult bit!

You can only find these commodities in mission rewards. I have found that running missions from LHS 2260 in particular the MCCLINTOCK GATEWAY to be very useful for this. Simply pickup boom delivery or cargo missions and deliver cargo.

One thing to note is always check the missions board after you have handed in your mission as most of the time there is a modular terminal reward mission at that station. It seems you can daisy chain these with each mission hand in.

Be on the look out for these types of missions. If you see the number 4 in parenthesis, then that usually means the reward is x4 modular terminals.
