The quest cannot be completed cause the area is not done yet. This is still the third update, and i'm the only developer, so there isn't a whole lot of content (as this is month 6 of development). (Granted there is much more content than on most average adult games)
There are some issues, so I go fixing them as soon as I find them. Keep in mind the game has over 50 different systems. So there is a lot of testing needed.
Onyx blackguard and Prison enforcer aren't in the game yet, as they come in future areas (but sometimes when I'm too burned out to do other stuff I create enemies). White Spectre is on Central ruins, it is an elite. (So far the only overleveled elite)
