This one is really only of interest to those of you who are playing World of Warcraft with me and have been running around the insect nation of Silithus for the past few nights gathering twilight gear, signets, crests and all that other crap in an effort to get in nice and friendly with the Cenarion Circle. If none of that made any sense to you, don't worry, you're missing very little.
Anyway - the twilight/crests/signet thing is covered here
which includes the total number of everything needed per person to get all the quests done.
More interesting is the quest line that will start once the gates are opened
