there's some good stuff on troll culture in this thread here!
and if you wanna know more about bluebloods, I'd suggest looking through the completed quests forum here, to get a taste of how they might behave! Personalities aren't dictated by blood color, but they often have a great impact on how a troll behaves!
Bluebloods fall towards the privileged side of the hemospectrum, which goes from red (lowest) to purple (highest). But just because they're of "high" blood doesn't necessarily mean they act that way. For example, I have a redblood troll who loves fancy things that might be considered "highblood" culture.
I guess what I'm trying to say is, don't let the blood color dictate your character! It should influence them, but don't let it force you into a box! biggrin
