Aeldar Gods are living weapons

• Liber Chaotica:

"I watched as the First Ones encouraged the younger race to reach further into the other realm and with their vibrant minds and passionate souls create beings of power to fight the star gods.

But the battle was long and the First Ones were now few, and as their numbers dwindled so too did their influence over their young creations. Without the wisdom and might of the First Ones to bind them, I saw the Eldar's warp-beings evolve from sentient weapons into living gods – the first true gods of the Immaterium. How I wept when the Eldar embraced them as such."

• Liber Chaotica:

"Time moved onwards and I saw the rise of the brother heroes, Eldanesh and Ulthanesh, who alone, in the absence of the First Ones, could control the Warp Gods and summon them onto the physical plane. I saw them march to war against the silver-skinned Yngir, the star gods and their slaves, and I saw them summon the dread lord Khaine, The Elder’s mighty god of war, to battle with them."
