Tiefling

Tieflings, are sentient humonoid creatures who have magically been displaced from their original homes.  
Refugees from a foreign world The Tiefling were able to make contact with human mages in 0 CY due to the temporal boundaries between worlds being weakened by the opening of the dark portal. Offering to ally themselves with Humanity in exchange for asylum The Tiefling became an integral part in the resistance against the demonic hordes during The Invasion. After which humanity upheld their end of the bargain and allowed them an enclave on the Mythril Penicula. 
==History==
The Teiflings origially inhabited a world much like our own until it was ravaged by a demonic invasion which corrupted a large portion of the planets population and left it in near ruins. During the invasion of The Realm the dark portals which had been opened to bridge the demonic hellscape to our own world weakened the fabric of reality enough to allow Mages the ability to communicate with Tiefling Seers and oracles on thier native world. The information telepathically given by the Teiflings were instrumental in the defeat of the demon armies and mages were eventually able to channel enough magic to open portals to the Tiefling homeworld and invite them into ours. Over the next 300 years more and more Tiefling refugees were brought to the realm and allowed to settle in the reach.
==Technology==
The Teiflings learned to shape crystals for all kinds of purposes ranging from power containment to data storage.The purple crystals often associated with Teiflings that decorate their buildings, weapons, and armor are known as arcane crystals and are used to power everyday draenei society.
