Nyadra'zatha, the Burning One was a C'tan who revealed to the Necron how to access the Webway with the Dolmen Gates, because it desired to bring his eldritch flames to the webway. A shard of Nyadra'zatha was later discovered by Trazyn the Infinite on the world of Midgardia. In the ensuing battle, Trazyn raided the world and was able to acquire the shard.
