Shiny Silvermoon

Well, since you asked...

In the Age of the Ancients, the world was unfounded; covered in a murk of fog, home to archtrees, grey crags... and everlasting dragons. But then... there as fire, and with it, disparity. Heat and cold. Life and death. And of course, light... and dark. And from the dark, four beings rose to claim the Lord Souls within the flames. One of them being Gravelord Nito; the First of the Dead, in a world once ruled by immortal beings.

With the strength of Lords now in hand, Nito fought in the war against the Everlasting Dragons, alongside Lord of Sunlight Gwyn, the Witches of Izalith and her Daughters of Chaos, Seath the Scaleless, and the Furtive Pygmy... so easily forgotten. Nito unleashed a miasma of death and disease upon the dragons, and alongside the four other Lords, the Everlasting Dragons were no more. Thus began... The Age of Fire.

The other lords sought glory, knowledge, power; building kingdoms and immortalizing their names in the new era, but Nito remained mostly distant. Only spreading death and disease throughout Lordran, in the Tomb of the Giants where he rests to this day. But as the Age of Fire seems to be coming to a close, he is fought by and ultimately vanquished by a Chosen Undead. A hero who will claim the Lord Souls from the now withered and old Lords of the past, and Link the Fire with them, ensuring the eternal continuation of the Age of Fire, allowing life to continue, and for the undead to finally lay to rest for good.

... Or, that's what Frampt would have you believe, anyhow. Now that my little novel is written, please, do tell me about these Tyranids! I actually only have a rudimentary knowledge of them.
