Thuyela

"The worst of them all are the Space Wolves. They were animals, Great Terra, they were animals those things that fought with us. When you have sympathy with the enemy, you know you have the wrong kind of allies."

- Combat Master Pawel Korine of the 40th Expeditionary Fleet of the Great Crusade

Thuyela was an Eldar Craftworld of unrecorded but probably minor size that survived the Fall of the Eldar and was encountered by 40th Expeditionary Fleet of the Great Crusade at an unknown date in the late 30th Millenium, in an area of the galaxy designated as simply Kobolt space. It was utterly destroyed by the Space Wolves Space Marine Legion.

History
During the Great Crusade in late M30, the 40th Expeditionary Fleet encountered a race of xenos in Kobolt space that were lethal and proud, and had no interest in human affairs. The xenos base of operations was a great transparent vessel that the Imperials remarked that it sparkled as if it was made of glass, and so was nicknamed by them as "Scintilla City". It was a Eldar Craftworld, and was called Thuyela in the Eldar language.

True to their capricious nature, the Eldar of Thuyela attacked the 40th Expeditionary Fleet without apparent reason or explanation, and managed to fight the Imperial fleet to a standstill. Fleet commanders called for the help of the Space Marines. An unrecorded number or Company of Space Wolves answered the call and quickly overcame the xenos. As "Scintilla City" shattered around them, the desperate Eldar realised that all would be lost if they continued to fight, and attempted to plead for terms. Imperial commanders involved in the action may have been content to naively negotiate a surrender, but the Space Wolves were not. Thuyela was sacked and its people slaughtered by the Space Wolves. It was so completely destroyed that there was nothing left for the Imperial forces to recover or plunder. The fate of Thuyela's survivors (or if there were any survivors) is not recorded in Imperial records. Senior commanders of the 40th Expeditionary Fleet were so horrified by the incident that they were left with a disinclination to call upon the ferocity of the Space Wolves again, until they were forced to do so in the assault upon the Olamic Quietude homeworld not long after.
