Here's a short guide to the role of the jedi consular.

A Jedi Consular (also called a Jedi seer) was, like all Jedi, skilled in battle, but rarely entered combat, preferring to study the mysteries of the Force.Consulars were the primary scholars and diplomats and seers of the Order, often becoming instructors.

What the Jedi Guardian preferred to achieve by combat, the Jedi Consular achieved by words or the Force. Traditonally, they wielded a green lightsaber, but, like all Jedi, they were free to choose their own color for the blade if they wished.

When they attained the rank of Jedi Master, consulars became known as Sage Masters.

Two Sage Masters joined with two Warrior Masters to build the initial Jedi Temple on Coruscant.

Notable jedi consular are Depa Billaba, Kit Fisto and Adi Gallia,Kreia, Jocasta Nu, Leia Organa Solo, Shaak Ti, Yaddle and, the last but not the least. Yoda (who was considered the best lightsaber duelist of his time even if he was a consular).

Dark Jedi Consular are also called Siths Lord.
