DirgeOfCerberus111: Xeno Race -"Titans": A race of titan sized, humanoid, mechanical xenos made of similar "living "metals" as Necrons (hence the name Titans). Tens of thousands of years ago they were once a great empire but due to an event called                  "the hundred days of fire" they descended into civil war. Now they are obsessed with absolute war and its every Titan for himself. Titans will only fight other Titans because... first: they can not truly kill each-other, second: they are the only worthy enemies they have. The Imperium sought to mine their worlds (they were insanely rich with precious metals) and because of that they couldn't use Exterminatus to destroy them (virus bombs would have no effect). So they invaded, however they moment they opened fire and interrupted a Titans duel ... all Titans on the planet stopped battling and marched on the invaders and obliterated the Imperial forces. The Imperials stood no chance for obvious reasons and because Titans are impervious to even the most powerful artillery. After-wards the Imperium found that it can mine they planets...as long as they don't bother the Titans. They once used ranged weapons but they cast aside such weapons completely, instead favoring melee weapons instead. But even these are rare as thousands of years of constant battle have reduced them to fighting with their fists. They are made of a living metal similar to necrons, so when-ever a titan "dies in battle" they simply repair themselves and rise to fight again.

I Don't know for sure if I'll use it, if anyone wants to talk to me about it. : )
