the eternity vault
the eternity vault is the first operation in swtor. relatively easy once you have completed it the first time around and work out the mechanics. The operation consists of a fair few trash mobs, 4 bosses and a puzzle in the middle of the operation that once figured out becomes a bit of a joke.

we recommend that at least one player in the team has the iphone app for this part of eternity vault. it is actually very easy to complete. you can find the app by searching the app store for swtor pylons. it should be the only thing that shows up and is a free app.
