Jedi consulars seem to fit into the mold of the "crazy old wizard," since they are much more adept at channeling the Force than are the other two classes. They don't gain any special Force powers when compared to the other two classes, but do gain Force powers at a very slightly more rapid pace than do guardians and sentinels, and will have a deeper pool of Force points to draw upon when they need to unleash their powers in combat. They spend less time training for physical combat, however, and so are not going to be as appropriate as front-line combat troops. A good example of a Jedi consular, albeit a Dark side example, is the cronish Emperor Palpatine from Return of the Jedi.
The consular's unique Jedi Feat is Force focus, which lends a bonus to the DC of their Force power attacks. Since this is a passive feat, it is always active, and will help your characters stun or incapacitate their opponents.
In addition to the normal Force power that's gained at every level-up, consulars also gain an additional Force power at levels 5, 9, 13, and 17.
