There is within the House many Tiers or Levels of Initiation knowledge and power. Below I have compiled a list of of the three most common Tiers.

A'ventu - Which Means "To be Awake"
A'eles -  Which means "To Sleep"
Erani'ata - Which means "To Know"

The Erani'ata are those who have married or been adopted by members of the House but who do not have the House genetics. They often have close associations with many members of the House.They may call on other House Members for aid and often carry with them tokens and gifts from the House granting them limited access to some power or ability. They are called upon to fulfill the First Env'at of the House.

The A'eles are those who are born into the House or have received some of the gifts of the House by some means. They may have latent abilities and are almost always immortal in that they do not age beyond their prime, but they do not have the ability to directly call on the Silverflame or gain access to the Higher House powers. Some of them have wild talents and are Stronger and faster then mortals. They are called on to fulfill both the First and Second Env'at of the House

The A'ventu are those Members of the House who have received the E'lavshtu or the "Opening of the Eye" Ceremony. These are the House Members who have access to many of the powers of the House and have the potential for learning many more. They may call the Silverflame and access many powers to learn and master. They are called to fulfill all three of the Env'at of the House

Each of level of initiation bears a responsibility that is part of the "Env'at" or "Concepts" of the Credo of the House.

The First Env'at called "Sip'etu"  which means  "To Do and Say" is to Defend the Honor of the House. This means they have a political and personal alliance with the House. They should try to forward the Causes of the House, defend and aid others members, and assist in promoting knowledge of the House.

The Second Env'at called "Lashen'tuset" which means "To Live and Grow" is to Live  in such a way as to be exceptional, never satisfied with where  you are and what you have, to thrive in new knowledge and new experiences, to go out and Live life.

The Third Env'at called "Meldearin" which means "To Change" is to use the powers and abilities that the E'lavshtu grants to them not only for their own benefit and that of the House, but for the Sheer joy of it. These Members should go out in disguise and Do things, from teaching a child a simple spell for the beauty of it; to changing the direction of a river so that a drought ridden village may have water; to the calming of a Volcano. Their passage through realms and worlds are the stuff of which legends are made.
 

The rankings and Env'at beyond this point are not currently held by any member beside Teloric and as such need not be listed at this time.
