 (< the Hethar Karad >)
     The Hethar Karad, the Servants of Greatness, are the devotees of
 Isskarazh, the Great Mother of Dragons.  A member is called a Heth Karad.
     The Hethar Karad have a communication channel accessed using the commands
 'hethar', 'isskarazh' and 'assoc'.

Seems to grant access along these lines:

 +2 Antagonism
 +2 Astrology
 +1 Demolition
 +3 Eructation
 +2 Intimidation
 +3 Legend Lore
 +1 Massive Blow
 +1 Massive Exertion
 +3 Piety (1 req)
 +2 Theology
 +3 Xhax (1 req)
 +3 Metaphysics (cumulative only)

Eructation access may scale with Piety. Metaphysics access is likely (but cumulative only), given that all the other skills she trains have spec access, but someone needs to test this.

Joining requires that you gain Isskarazh's positive regard: this may be acquired by killing things that attack dragons, srazhs, etc. and by succoring dragons, srazhs, etc. Being a draconic race (Zuth, Srazh, Dragon, etc.) will net you starting regard. You may also purchase regard using Lux.

You can lose regard by killing draconic things:

Klethka hisses, (< You wish to know of the precedence of the nobility of mortal
beings in Isskarazh's eyes, Benerius?  Your interest in the proper order of the
world speaks well of you.  First are dragons, second zuthar, third drachannach
and srazhar together, fourth are wyrms, fifth drakes, sixth llelimin, seventh
firelizards, and eighth and last are chimerae. <) at you in Xhax.

Attempting to join with insufficient but positive regard will report your progress towards the necessary regard, at a resolution up to 1/100th of the progress. Experimentally, succoring a drachannach five times is about 1/100.
