Bungie, I don't know what your current stand on possible future Ghost customization is, but when on patrol or just doing random PvE activities I have found plenty of dead ghosts containing Grimoire card information. I have also noticed that some of these ghosts, one of which I found on patrol in Old Russia, have different colors. What I was theorizing is that any dead ghosts that you find that happen to have a different shell could be bought from maybe the Speaker for Motes of Light or from Xūr for Strange Coins. This would motivate players who hadn't already found them to do some dead ghost hunting and it could give players an incentive to view the Grimoire reading that they had just discovered and delve deeper into Destiny lore. And maybe, just as a super cool add on, certain ghost shells could alter the voice of your ghost. Just think about it, a ghost that sounds like Clint Eastwood, or Ian McKellen, OR FREAKIN GOTHALION OR DEEJ WHATEVER THE HELL YOU WANT. Just a cool concept, keep up the hard work Bungie!
