Homebrew Athari Species Details

Many Limbed Masterminds

Athari are spider like in appearance and stand roughly at the same height of and elf with the same lithe build. They have four spider like arms all the same lengths but with some humanoid features like their seven fingers that despite being hooked at the end can still be used to manipulate objects with far greater ease than other races. They have feet that posses three long toes at the front and a larger on all of them are clawed to a degree and when combined with the hands they can be used as a deadly weapon or allow for quick climbing. The Athari also have incredible minds one of the only reasons as to why they have been able to remain civilised in the underdark. Their intellects have allowed them to create advanced technologies that allow them to effectively seal themselves from the outside world. The Athari also reproduce asexually laying a single egg every 10 years, this egg takes 1 year to hatch and the Vethari that hatched takes 20 years to mature to the point where they can also lay eggs. This very low birth rate means that the Athari have to hide and develop new technologies to protect their young less they be found and culled by the other more numerous races. Despite this immediate disadvantage this means that if even a single Athari survives they can in theory restore their entire race.

Vethari Sanctuaries

The Athari live in large spherical structures called Sanctuaries. These cities use magic to create artificial gravity to allowing its inhabitants to walk along its surfaces. These cities have other spheres within to increase the space available all of them kept aloft using magic with some non magical failsafes in the scenario where the magic is disrupted. These spheres have artificial ecosystems inside and are perpetually dark to ensure that Athari always have the upper hand in the event of an attack. Thes spheres have everything the Athari could need such as facilities for scientific advances ect. The outer shell of the sphere often contains the agricultural areas used to sustain the populace. The second layer often contains the industry and science areas. The third layer contains the housing and homes of the Athari and may also contain leisure areas. The fourth layer will contain the hatchery this is one of the most heavily defended area. The core will house the command centre which oversees the entire city. 
These cities are hidden under much rock and only those who try will ever find a sanctuary but those who do so with ill intent will be immediately dispatched by an array of advanced technologies. 
The Athari Weave

The Athari themselves are living sources of magic. They do not rely on the weave or any other source of magic aside from themselves. Each Athari has their own self sustaining source of magic. The Athari access this magic by using their own webs to create a miniature version of the weave most other spell casters use, they then use this miniature weave to access their own innate magic in a controlled manner. So powerful is their internal magic source that if they were to cast a spell using the normal weave then they would most likely overload that part of the weave and disrupt it causing spells in that area using the weave (including their own) to have unpredictable affects until the energy dispersed. This source of magic can be given the credit for their extremely long life span that allows them to live for 1000 years without deliberate life extension. This special weave allows the Athari to develop differently to the other races due to never having suffered from the spellplauge directly. Athari spellcasters cast a spell by creating a artificial weave using their silk to cast a spell using their multiple limbs to manipulate it in accordance to their own desires. 

Athari Traits

Athari are well adapted to their way of life in the underdark.

Web weaver

With this trait a Athari character can use vethri webbing to produce goods, repair clothing and with sufficient quantities and the correct spells, entire buildings or vehicles. 
*Please not that the amount of silk required to build, repair or produce varies depending on what you want to make. The amount required will be decided by the DM taking into reasonable consideration your skill as well. 

Silk Production

On demand you can produce some silk. This silk possesses many wonderful qualities and can be enchanted and modified in a variety of ways.

Every time that you eat a meal you can choose to convert it into silk or digest it like a normal creature. The amount of silk produced is half the amount of food eaten. 
For example if you eat 1000g of food you can then either digest the food or produce 500g of silk, this silk can then be stored and used later.

Languages

You know undercommon, common and spinner script. 
spinner script cannot be read by none Athari.

Spinner script is a language devised by the Athari to hide their secrets and mark the path ways to their cities. The do this by wrapping something in a special silk that they indent using magic. An Athari can feel these indents and discern the message on it. When an Athari speaks spinner script they do so by playing the plucking Athari silk to produce sounds that form the language. Due to their advanced intellects they can pluck multiple strings at once to speak quicker.
