I have noticed that they are grey. All creatures big and small that you attack that are blue you lose karma. For some reason they lack this flag. This becomes an issue when I noticed that the Cu Sidhe DO attack evil karma charactors & the ones near the karma line do NOT attack the changlings, as do the Dryads and Pixies, ( Unicorns and Kirins if released.) As a result of them attacking ME on some chars I then lose more karma and the creature in question is not even blue.. While we are talking about Karma relations the line of good -evil seems to be blurry to paragons. If you are at the very edge on the good side still and RUN near a paragon they attack... If this creature is a evil paragon then they attack you anyway. But with the Cu Sidhe being grey (non blue) + Paragon and run by they too attack.. Pixies and Dryads Uni's Kirins. If you are on the line of the Karma bug and DEFEND yourself from them,you are then pushed over the line.
