I'm glad you guys are enjoying this!
Now the Cacame section of the campaign was only a few dozen pages, I meant the thing as a whole. (At the moment the party is in the Taklamakan desert. They found the legendary being but... he's lost his memory! They must help him before he can help them).
After placating my players and "re-railing" the campaign, the party crossed the Karakum desert, dealt with pesky trolls on the way, and reached Merv, which based on some historians was the largest city in the world at that exact moment (only to get sacked later...)
Merv went through several "generations", with the better and newer ones being where the well off lived, and the semi abandoned ones being left for industry, the poor and the second class citizens.

The party rests, buys supplies and do research for their quest. The dwarven party member makes contacts with the local community, and manages to get himself invited to a secret midnight meeting - where Cacame is present! Cacame tells the dwarves:
"Dwarves of Merv, heed my word. I bring news, both dark and bright. The winds of war are blowing. Sanjar grows old and weak, and so do the Seljuk. Alliances against them are being formed. New warlords are rising, looting, burning cities. The moon grows dark. The walls of Merv are either faded hills, or fancy constructions of brittle mud. You have no safe shelter here.
But there is hope. South of Nishaput, there are several ranges of hills and mountains. 7 clans have claimed these hills. They have formed an alliance - the Confederacy of Ferns (Ferns culturally significance - symbol of endurance and community). I am Cacame Awemedinade, the Immortal Onslaught, and I lead the confederacy. I have come to offer you all safety in our hills. There is room for all of you. The hills are rich with copper, iron and turquoise. This offer comes from all the clans - we will provide you shelter and protection. I know that this is very different than living in the shadow of Merv... but let me tell you, the shadows cast by a mountain are far fresher - the air is clean and the moon closer. Join us!"
This causes great excitement and consternation among the dwarves of Merv, but the meeting is interrupted by alarming news: Soldiers of the local Seljuk ruler are surrounding the dwarven quarters. They claim they are imposing a quarantine due to a plague - but there is no plague. The dwarves deduces that the Seljuk Governor somehow learned that Cacame is present, and wishes to imprison him. The quarantine excuse is but a cover story. Cacame is confident that he can break through... but he will have hundreds of soldiers hot on his heels.
The dwarven party member (Wutzi), with the help of a grubby "dwarven" follower of Cacame (Grasnol... a goblin disguised as a dwarf with a mixture of a fake beard, a pillow under his shirt and a few illusions) manages to sneak out of the dwarven quarter. Wutzi rejoins the party and concoct a grand distraction -they break in the army's stable, slay the guards and "liberate" over a hundred warhorses into the city street, causing mayhem. The confusion and commotion is enough for Cacame to break out and gain a league's lead over his pursuers... which is enough.
The party promptly leaves Merv as well, never to return. The local authorities investigate and discover it was them... but they too have a long lead, and the Seljuk never manage to catch them as they flee past their influence.
And that was Cacame in my campaign
If you want to see Cacame's kingdom, look at Neyshabur in Iran in google map and turn on the terrain mode:

Lastly, I'm surprised no one asked whom the dwarves were meant to be
