My my , haven´t seen that Kwlloch has frostfolk and werecreatures. Changes to 6 tribes of goblins, 3 tribes of hobgoblins, 1 bugbear, 1 frostfolk, 1 werecreatures.
Frostfolk are frost giants or are there others from the PHB that are usable?
Contribution:
The plateau of Kwlloch is mostly inhabited by the goblin tribes. Each tribe has a council of Blues who appoint the chieftain of their tribe and the war chief. The council doesn´t rule the tribe directly but interpret the omens of the Twelve. Of course these omens are always obeyed but it happens that the council disagrees on the interpretation. The Twelve are seen as the mythic founders of the tribes and are worshipped as ancestor gods. Their teachings are not outright evil, but have a certain cruel bent.
The tribes are named after their mythic founder. the smalles tribe are the Amalak. The tribe is a special one, as its members are mostly Blues. The Amalak tribe are the lorekeepers and psions who live in Ktarr. The nyalak and cyalak are all members and outsiders are forced to enter the tribe and foreswear all other loyalties and oaths besides their vows to the Twelve.
The Ktoch tribe is the smallest wandering tribe and the second smallest one. They are hunter gatherers and don´t keep many animals. They are fierce fighters though.
The Matrekh and Kethera are nomads with elk herds. They are medium sized tribes.
Kethera was a female founder.
The Dasra dwell in and around an ancient dwarven city that was founded by the same survivors who founded Kesh. they keep an enslaved kobold population for agriculture. The vast subterranean fields, heated by thermal springs, enabled them to grow to an impressive size. They also claim vast tracts of land around the city as their territory.
Dasra is also a female founder and worshipped as some kind of fertility goddess. The other tribes think of the Dasra as weaklings, only able to hold on their territory through cunning and intrigue.
The Ktam are a special tribe of outcastes. Exiles from other tribes often wander to the city of Ktarr and join them. The tribe was founded after the original tribe was annihilated several centuries ago, by an eyrian expeditionary force, sent to punish the tribes of Kwlloch. The few survivors fled to Ktarr and merged with the outcastes. The Blues declared these amalgam the new tribe. Exiles from other tribes are freed from their old obligations and crimes when they join. As a symbol of this rebirth, the goblin takes on a new name and carves the sign of his new tribe on his left cheek. The Ktam concentrate in the city of Ktarr as their main seat but the majority of their population lives in villages around the city or tends to the herds of goats who are herded to the mountains in the summer.
The Kurgha are the largest tribe with several semi independent clans. They settle in caves and old outposts, wander the plains and found small farming villages. These villages are often target for raids from other more coherent tribes but their importance and size has kept the kurgha from being subjugated. The Kurgha are the primary traders of the Kwlloch tribes, some of them are welcome in the the borderlands of Eyros or can even travel further.
