I'm rather enjoying having a noble around the colony. She's Ascetic so food and bedroom quality doesn't matter to her, though she still wants a nice throneroom, but that's rather manageable. In return she can mass debuff enemies and is allowed to wield a damn good sword, and gives periodic mood bonuses when she holds concerts or speeches.
Got way too many link weapons though, the empire keeps giving me them for babysitting animals and random noblemen, and most of the colony can't use them. I'm tempted to start making more of them nobles just so I can give them link weapons without fear of reprisal.
Need to get cults/religion back online so I can have a full royal court.
EDIT: So the psychic harmonizer implant gives out a mood penalty or bonus to all pawns near the implanted pawn based on their mood. Currently have one in my Countess, more for theme than effectivess since there are other pawns who tend to be happier than her, but I've been thinking about how to use one more effectively.
Obvious first thought was to stick it in an optimist, make them radiate those good vibes.
Second thought was that a masochistic cannibal or something would be even easier to keep happy than an optimist by inflicting pain on them, feeding them human flesh and drugging them. They'd radiate a buff by sharing the pleasure they feel at being a tortured, drugged up psychopath to all nearby pawns.
