Homebrew Colliatur Species Details

Crystal Scourge or Salvation?
Colliatur are Aventyrians that drank from waters carrying a pathogen designed by one of the world's first masters of magic, Udodeling, released through Underworld streams and to the surface above. These microorganisms cannot completely stop the advance of the alien biology's invasion of a host body, but they do prevent them from becoming completely sublimated to the otherworldly entity's will. The limited time available to the undead wizard prevented wide dispersal of the anti-collod virus, leaving the extraterrestrial sentience puzzled by how any creature could resist it's psyche (there is a 1% chance that a PC has been exposed to this otherwise benign virus and is immune to the detrimental effects of the colloid). Colliatur are ofter found leading the subjects of the colloid-their independence proving to be an attracting force to the alien's thralls-and may be encountered anywhere in the Underworld or Upperworld.

History
The colliatur are a new race to the world of Aventyr, created by the mad designs of Udodling after The Confluence. Their "parent", the colloid, is a creature from the far flung start of the cosmos and unlike any other on Aventyr (even the hoyrall, though they share some eerily similar traits). A collective intelligence that rivals deities in its mental powers, it sensed the mass transposition of life forms across the galaxy during the Great Schism. For centuries it studied the conduit maintained by the alien half-god Exis, engineering a means to take that power for its own.

Eventually the colloid's chance came; though incalculable machinations for nearly any other entity, the colloid seized the half-god Exis' divine connection the hoyrall, subverting it to catch upon an asteroid headed for Aventyr. The hive-mind of the alien insects in both Underworld and Upperworld was destroyed instantly, and as the bizarre entity hurtled across the galaxy, their societies fell in upon themselves.

When the colloid and the meteor it used to traverse the cosmos landed in the First Hive, the overload of stimulation in its reentry to the atmosphere left the alien entity confused and distraught. In the onslaught that ensued, thousands of hoyrall died as the colloid rampaged away to solitude far below in the Underworld, where it could regain its senses of purpose and understand all that had occurred since it's relatively quiet journey across the stars.

As it re-assembled itself and reencountered sentient life, the colloid began to understand more of what had occurred and recognized the great threat represented by the necromancy of the first lich, Udodling. Centuries before he had fled below the surface of Aventyr, taking refuge in an undertower near the First Hive.When the colloid landed in the Underworld, his shambling minions where the first formidable force the alien encountered and the hatred it feels for all the undead knows no bounds.

Before the colloid could reach and consume the obsessed lich, the undead wizard managed to enact one of his countless ploys to undermine the alien entity. Though the ancient mage's mastery of biology was largely useless to the creation of an entire race of undead, he was well-suited to craft an organism which could aid the living against the otherworldly entity.

After fleeing from the colloid's arrival in the First Hive, Udodling crafted a grand undertower that stretched far into the bedrock of Aventyr, a place where th thought only his kin could survive. For decades he employed advanced arcane techniques and powerful spells to hone his craft and eventually, using the bacteria and countless other creatures invisible to the naked eye, Udodling created a microorganism tailored to modify living tissue to resist the colloid. Immediately, the undead mage set off to disperse his fabrication across Aventyr, releasing batches of the creatures into the many waters of the Underworld. While he was away, the colloid discovered the location of Udodling's undertower. The colloid lay in wait, and on the mage's return struck a fatal blow. Udodling did not survive to create more of the virus, but enough propagates that the colliatur have begun to appear all across Aventyr.

Physical Description
Colliatur appear much like the base creature does, save for a few subtle changes. Their hair has several strands that are crystalline, their pupils appear to be distorted  into the shape of many pointed stars, and their fingertips become reflective and metallic. Perhaps most disturbing of all, the teeth of all colliatur are a perpetually clean, stark white.

Society
These children of the colloid are inclusive, kind and friendly to all races. When left entirely to their own devices, colliatur are disturbingly quiet and seemingly lethargic, though they're more likely to be in deep contemplation. There is little celebration for the arts or purportedly impressive deeds, but the few stories told of settlements of their kind speak of architecture that defies understanding and resonances that shake men to their cores.

Relations
Most upperworlders and undersorlders greet the colliatur with open arms, accepting their warm embrace with either a hidden blade or hand out for mercy. Their tendency to deeply value life make them fast allies in both cases, but their hatred of undead make them mortal enemies of the dodeling. Hoyrall that recognize them for what they are will attack them instinctively (which anyone who knows their true purposes is wont to do so). Despite all of that, aside from the dweorg, they are the most celebrated and desirable race from the Underworld as far as most of Aventyr is concerned.

Alignment and Religion
Colliatur typically gravitate towards the Neutral alignment over time, but may be of any alignment they please. They rarely worship any of the gods, instead gaining quasi-mythic abilities from the colloid. Those few that turn their backs on the alien entity find solace in He who Renews, Eureum.

Adventures
Exploring is a natural impulse for the colliatur, and spreading the message of the alien overmind is their first priority. Spellcasters are common among them, but warriors of particular prowess are frequent as well.

Names
Colliatur tend to keep the names that had before their transformation.

Note:
You will need to manually add the languages spoken by the colliatur's base race (other then Common).

Colliatur Traits

Ability Score Increase, Acid Conversion, Conductivity, Crystal Refraction, Darkvision, Parent Race, Sacred Life

Ability Score Increase

Your Charisma score increases by 2 and two other ability scores of your choice increase by 1.

Darkvision

Many creatures in fantasy gaming worlds, especially those that dwell underground, have darkvision. Within a specified range, a creature with darkvision can see in darkness as if the darkness were dim light, so areas of darkness are only lightly obscured as far as that creature is concerned. However, the creature can't discern color in darkness, only shades of gray.

Acid Conversion

Your organic parts may be hurt by acid, but your crystalline parts are capable of converting it into life. As a reaction to taking acid damage, you may regain 10 hit points on your next turn. Acid damage can never kill you, only knock you out.

Conductivity

While your crystalline structure provides a lot of benefits, it also conducts lightning much better than flesh and bone. If you take lightning damage, you suffer from disadvantage on Dexterity saving throws for a number of rounds equal to your Hit Dice.
