Operator Module Embla-6, im thinking is going to be on the more idealistic end for something like this. but a bit paranoid as a survival strategy. Skilled spaceworker, actually knows shit about spacecraft and maintenance. On a quest for answers about the fate of the Cloud.

Embla is doubtful that the card will actually work, but is still taking the risk as it might be useful (if extremely dangerous) leverage if it even unlocks control of some of the ships systems. 

So, looking for relationships, Embla has spiritual beliefs (Technoshamanistic) and is most closely tied to the mining union.
