Homebrew Ghost Diamond Gemticore (by Baskerevil) Species Details

Creation Myth

An old legend is still believed in Gemticore society. It tells a story of a half-elf, half-dragon, and half-giant fighting against mystically empowered Manticore. The battle ended with all four dying, but as their blood and soil beneath them mixed, a new type of creature emerged carrying the legacy of the four who fell. Either truth of fiction, Gemticores embrace traditions, customs, language and everything they can based on the foundation races. Therefore, society of Gemticores circle around various different aspects of dragons, giants and elves. 
Almost all individuals of this race live in a pocket dimension island which resides on an intersection point of various worlds and realms, so, sole individuals of this race could be found in different worlds going on a trading trips or gathering diplomatic information, however, very few strangers are invited back into Gemticore Realm.

 

Society

Gemticore society is interestingly structure. It is split into three spheres of influence: economical, magical, and militaristic.
Economical part of Gemticore society is ran by mostly "Emerald" Gemticores: focused on trade, various forms of crafts, and even typically responsible for diplomatic relationship with various world and nations. This part of Gemticore society is the most open to other cultures and lead by a council of "Emerald" Gemticores. This council is elected through democratic process with all artisanship leaders voting in secret.
Militaristic part of Gemticore society is ran by almost exclusively "Amethyst" Gemticores who are enrolled into various combat training schools almost since birth. Male "Amethyst" Gemticores are trained as foot soldiers and Female ones are trained as tacticians, leaders of military actions. This part of Gemticore society is very strictly segregated by gender and follows the most rigged rules in Gemticore society, though, there are few good reason to do so. Gemticore native realm often being assaulted by various cosmic threats and thus having a strong military is essential for their race to survive.
The last part of Gemticore society is ruled by any Gemticore who possesses aptitude towards magic, though, it is mostly "Ghost Diamond" Gemticores. This part of their society focus on researching magical forces, creating magical items and trying to create more powerful magic to assist their own society. Members of the magical society are very secretive and prefer to do their own research without involvement of anyone else who could steal the credit and research material, thus it "Ghost Diamond" Gemticores prefer company and assistance only from those who do not possess any magical abilities.

 

Biology

Gemticores are natural creatures to their own plane, however, they have very little interaction with creatures of other planes. It is not known if Gemticores can reproduce with other races, though, it likely some other creatures (like dragons or orcs) might have a compatible biology.
Gemticore biology is quite unique. They start their lives as eggs, however, after hatching the young Gemticores develop the same way as most mammals. They remain dependent on their parents for the first year of their life, but grow up fast. By the age of 1 they can already walk, fly, talk and even scavenge for food. They are blessed with a dangerous stingers, though, it start produce venom only when they are at least 3 years old.
Like true dragons, Gemticores do not become senile. After maturing, they do not change much and grow only more powerful with age. Their minds and fangs remain sharp even after a hundred years, their poison remain potent for hundreds of years, so, technically Gemticores could live for an undetermined amount of years. However, they have very limited amount of living space and a culture custom exists within their society that every member of their race either becomes exiled or end their own life on their 250th birthday. Therefore, it is very hard to research and know the exact course of their life beyond this point.
Right now Gemticores split into three distinctive sub-races: amethysts, emerald, and ghost diamond. There is barely no mixing between different variants of their own race, so in next few thousands of years these three could eventually evolve into different races, but right now they are very similar and differ in only few minor ways, excluding the fact each sub-race produces very different type of venom.

  

Ghost Diamond Infusion

Due to various arcane research, deals with cosmic entities, pacts with devils and demons, various horrific experiments, and other mystical activities, most Gemticores believe that their "Ghost Diamond" brethren are inherently cursed and that is why they exists in the form they do. Members of the sub-race typically possess innate magical talent, and most of them typically become sorcerers of various types. However, while not everyone of them are gifted in arcane arts, most of them have some innate magical ability and typically are very inclined towards mystical forces.
"Ghost Diamond" Gemticores fall into several profession based on their talents: magical researchers, various civil workers or undertakers. In Gemticore society members of this sub-race are not treated well if they do not provide lots of value for the society. If one is born without any talents towards arcane arts, then they are treated only slightly better than animals. It may be because of superstitious nature of their society, or maybe just because it is an accepted behavior. But those who do have talent - they join various ranks of colleges of magical research, get respect, admiration and various perks so that they could do magical research without worry. Magical society of Gemticores as overseen by four of their most powerful mages. Every time one of them retires a selection process starts and almost entire Gemticore society goes into a celebratory frenzy: festivals are held, various artistic events happen, sometimes even representatives of other worlds are called in. Four great mages are not only core of Gemticore's magical community, but also big part of their society as well, so an new one being chosen is a big deal.
