Talk with Herald Telcha at the zone in inside Chardok. He is smaller than any other sarnak you see and does not hit back. He appears to be rooted in place.

You say, 'Hail, Herald Telcha'
Herald Telcha says 'Hail to you, lesser being! It is good to see you seeking the enlightenment and satisfaction that can only come from serving the Sarnak! Experience for yourself the joy of fealty to our Lord the Overking Bathezid Dizok! I am Telcha, lesser apprentice sub-herald in training to the Court of Dizok and I stand ready to welcome those who would serve our noble Overking. Are you here to [aid] us ?
You say, 'I will aid the sarnak'
Herald Telcha says 'Ah, so good of you to strive to improve yourself! So often members of your pathetic lesser races plod along in ignorance, unaware of the most Noble empire of the Dizok. Enough though of the chit-chat, as Im sure you are most eager to make yourself useful! Before you may enter our worthy city and be looked upon as a valuable servant, you must prove your worth to our [cause].
You say, 'What cause?'
Herald Telcha says 'The first task I shall set you is the slaying of goblins! Ooh, how very heroic you must feel to finally have a worthy goal guiding your previously menial existance! Yes, go forth from here and journey to Droga, stronghold of our enemies. Slay the warriors and menials of the Mountain Death Clan, bring havoc to their homes. Return to me with proof of your deeds, to raise in your standing with the Dizok. Bring me [tokens] of many dead goblins, and one day you shall walk among us.
You say, 'What tokens?'
Herald Telcha says 'As proof of your deeds I shall require either 2 Mountain Death mineral salts, or a patch of green goblin skin. Bring me many of these, as you bring destruction on the goblin city, and I shall speak to my superiours of your efforts on our behalf. Do enough for our cause, and I shall reward you directly. Return to me later and remind me that you serve the Sarnak, and I may have a ring for you if you are worthy.

Hand Herald Telcha a Green Goblin Skin:
Herald Telcha says 'Green Goblin Skin! You have indeed been busy! I shall speak to my masters of this, continue your good work and return to me with more skins.
Your faction standing with Brood Of DiZok got better.
Your faction standing with Sarnak Collective got better.
Your faction standing with Goblins of Mountain Death got worse.
You gain experience!!

Hand Herald Telcha 2 Mountain Death mineral salts:
Herald Telcha says 'Ah, most excellent! You are sure to be more highly valued as our servant once I speak to my masters of this! Mountain Death Mineral Salts, they shall grace the Overkings table this very night! Be off, minion! Fetch us some more salts to prove your value!
Your faction standing with Brood Of DiZok got better.
Your faction standing with Sarnak Collective got better.
Your faction standing with Goblins of Mountain Death got worse.
You gain experience!!

Below warmly faction:
You say, 'I serve the sarnak'
Herald Telcha says 'Away with you! I am the herald of the Dizok Overking, here to greet the servants of my master. If you would walk within our city, go forth and prove yourself our ally by slaying our goblin enemies! Advance into our city at your own peril, as our soldiers regard you as a foe!

At Warmly or ally and below level 50:
You say, 'I serve the sarnak'
Herald Telcha says 'What to do, what to do.. You've served the Di'zok well, young one but you are not yet experienced enough to wear the Signet of the Di'zok. Come back when you've seen a bit more of the world, and the ring shall be yours.
At Warmly or ally and at level 50 or above:
haha, I will get there some day. I will let you know when I do.
