Stuck in Revelation main quest!

[Rafdragon]

I'm stuck in Revelation main quest. The misson says to Defeat The Starborn and has a optional to disable the defenses, but the Ecliptic Base Key is missing and I cannot open the door where the Starborn is. Fast travel is disabled during this part of quest.
Ony to know, During the quest I have choosen working with The Emissary Starborn.
Please, I need help to continue playing and finish the quest.
Thanks!

get far enough away from the computer you would use for defenses and look for another mission icon, there should be a key laying on the ground where ever you killed the starborn guy that opens that next door (if you remember where he died go there and look) - but it may be hard to see or hidden depending on where your standing (too far / too close)
