The above list is a bit outdated.
I am currently on a great Linkshell with some very fun and helpful people.
We play together pretty much nightly and have a lot of laughs while doing leves and while we are crafting.
I can't remember the name of it for some reason.
However, the characters Dior Digs and Willshire Mania both can give you pearls.
There is 30+ people on the shell and usually at leave 10 interchanging active players at any given time.
