That would be beneficial, yes.
OK - now we officially have two seperate sources of information...and, IC, the next time Justice and Xath fall asleep, suffice to say that there dreams are...disturbing.
Though there aren't any mechanical penalties or benefits as of yet, bear this in mind as you access the memories of the Bluestar:
1) You see everything therein from his perspective.
2) These memories are alien - wrong in a way that you cannot normally conceptualize. The more time you spend immersed in them, the more of yourself you will lose.
3) The memories are like an incurable cancer (at the moment) in that they may be able to be fenced in or contained, but they cannot simply be dismissed. If you leave them alone, they leave you alone, but every time you access them, it seems a little harder to force them to retreat. It may be possible to remove them, entirely if you wish - but it may not be. Without a doubt, the longer they live in your mind, the harder it will be to have them out of it.
4) When you sleep, you have nightmares, and because of the rings, you share them with the group. Unlike the normal dream state, these assault party members (once more, no mechanics) even when they are awake.
There may be more, but that's what I think is important to note right now.
