My attempt to describe culture and society.
--------
Culture/Society: Before our hero - the wizard - appared, goblins around Goldtier mountains were constantly fighting and raiding their next-door neighbors. Goblin villages had two tiers - most of the village was above ground, with hideouts and treasuries hidden underneath the village (into mining tunnels). This made goblin village looting rather difficult - one could loot on ground, but could not smoke out goblins (and their treasures) from underground.
There was a lot of bad blood. Most goblins were Living in small and backwards tribial communities and every village produced most supplies, that it needed for its survival, on its own. Constant raiding and attacking was considered "Normal" amongst population, especially during winter and summer, where not much could be done on fields.And goblins, well, they don't do so well, in doing "field work", smithing and engineering are quite a different story from farming tho. As every village needed armor and weapons - for raiding purposes - every village also had a smith or two. Two incase of one should die. Every village also had village elder, a shaman and a warrior leader. Village elder did simple things, like decided where to plant seeds or who works. Shaman explained unexplained phenomens, ate a lot of mushrooms (raw) and attempted to cure sicknesses and treat wounds (often in rather "creative" ways). A warrior leader was just that, what you expect him to be - in charge of training recruits, defending hme and looting neighbors. Villages never seemed to get along and rarely did alliance form.
Well, that was before our hero appared. With in few months, unnamed wizard managed to join 5 tribes and total 10+ villages under his dominion. And from there onwards it was a simple task of joining all goblins to work towards one goal. His goal. Goblins, being used to and highly focused in their specialization - for an example: a smith deals with smithing issues every day, 20 hours a day, with passion that can not be compared to other races. Under one leader, who was not as selfish or own-village and bribe friendly, this small "union" grew larger and larger. Goblins underneath Wizard soon nicknamed him "The Prophet" and followed his teachings and orders, like these would have come from Creator itself. There were only few times, when problems in serving our unnamed wizard appared. And "The Prophet" dealth with these "issues" with incredble speed and brutality. Now, no one questions Prophets will. No one questions prophets orders. Specialists work, singlemindedly in their area of specialization - smiths smith, woodcutters chop wood and warriors train in gigantic armies. They can do it now, because they do not have to worry about their safety anymore. As their safety is guaranteed by clan-union. Some of the goblins, even worship Prophet.
Turning these past two years, goblins have expanded their trade networks, they have gained great boost to their overall production and new villages are "converted" under Clan Union name every passing month. And with that, new armies, larger than anyone has ever seen or heared about, are being created. Villagers, now freed from their monthly working-raiding duties are being used to fuel this new machine of war and goblins serve well. They want to serve, because that is what they do best. And because they know what happens with those who do not obey to His will.
Religion: While most goblins believe in some sort of religion, no real region or even similar beliefs existed in Goldtier mountains. Some tribes did tell of a story of a Prophet. A Goblin Prophet who shall unite goblins, form an army out of them, conquer entire world and make everlasting peace last over the entire world. He would also greatly increase "home-brew" productions of goblin kind. Now, within the domination of Unnamed wizard, new cults are being formed, that believe that this greenskinned magican is the Prophet. Wizard has shown no differend behaviour, when goblins refer to him as prophet, king, master, Lord or even The Creator. It seems, this unnamed wizard does not care what he is called or believed to be, aslong as his orders are followed and he is respected.
While wizard himself is not interested in any religion, he does - sometimes - teach his subjects in arts of bending and controlling emotions. For an example, he sometimes visits recruit-training camps and orders recruits to stand in formation. He then casts a rather scary flame-spirit to attack these recruits. While recruits fight, he teaches how to hit these creatures and how one must control his fear - anxiety - lack of sleep - hate and even pain, and focus all feelings towards one single goal - to defeat opposition. Recruits are usually under-equipped and rather easly scared, many (if not all) flee. Those who flee are hunted down by veterans or by wizard himself and every third of them is allowed to retry the exam. Rarely are there more survivors, than 10 out of 100 recruits. But those 10 are stronger and more focused than they were before. By the end of the training, these soldiers are machines: they are not afraid, they are not scared, they are not angry - they have just one goal - to defeat their enemy and to follow orders, no matter if it'll cost them their fingers, other body parts or even, their lives. And this kind of a dedication is rarely seen even amongst "elite raiding-wars" veterans.
With every passing day, more followers that believe, that this wizard is The Prophet increase in numbers. They also believe that He has come here to teach goblins how to control emotions and wield them as tools. And this belief motivates many to work and to sacrifice their own lives for wizard. So often enough, wizard stops and tells a thing or two to civilians of how to control emotions and focus them towards one single goal. Of course, goblins do not know, that ability to focus all emotions towards one goal, is one of the essential skills in spell casting - without it, one would have hard time in casting anything larger than firestorms or tornadoes.
Values:
1) obeying wizards will (new, came out of fear and respect for wizards skill),
2) earning and increasing personal wealth,
3) working for a village (has shifted into working for the Clan-union, in fear of disobeying "Prophets" orders)
4) War - Has shifted from small time raiding to full-fledge war with anyone who is not from the Clan-Union.
5) Professions like Smith, Miner, engineer/inventor, warrior and Woodcutter are always held in high value in Clan-Union society. Alemaker, trader, elder and hunter are thought quite highly of.
6) In private life, families - focus on one certain profession and wealth are rather important.
