UNINVITED GUESTS
Very few mortal eyes have beheld the Garden of Nurgle. Its swamplands constantly wheeze a fog of supernatural diseases, and living beings cannot endure so much as a single breath of its repugnant air. Only Nurgle himself can spare visitors from his garden's toxic affections; when he is expecting company, he will open a path through the gurgling fungus-fronds with a single magnanimous gesture.
Trespassers are viewed poorly in Nurgle's domain, as the seers of Lugganath found to their cost. The Aeldari of that far-flung craftworld have long told the story of the Caged Maiden, wherein Isha, the goddess of fertility and healing, is imprisoned in Nurgle's mansion; there she is forced to imbibe Nurgle's most pleasing concoctions as her grotesque admirer observes their results with building excitement, and Isha's restorative powers ensure the process can be eternally repeated.
The Aeldari believe their myths to be founded in truth, and so it was that when Lugganath was ravaged by the Brittle Coma, a council of its most gifted psykers cast their minds into the domain of Nurgle, in pursuit of Isha, hoping to find their lost goddess and put a halt to their craftworld's deadly malaise. They knew that they would almost certainly die in the attempt, but believed that their souls would ultimately be drawn back into the glittering spirit stones of their comatose bodies. Once safe in their crystal afterlife, they could impart Isha's cure to the Spiritseers and lift Nurgle's curse.
At first, their astrally projected forms appeared to be able to pass through the grasping foliage of Nurgle's garden with ease. Their ghosthelms kept them as insubstantial as spirits and their rune- shielded minds cut through the dismal vegetation, for they were sharper than any corporeal blade. The rot-flies of that realm buzzed loud in alarm, however, and whispered of the intruders into Nurgle's ear. Just as the seers of Lugganath sighted Grandfather Nurgle's manse in the distance, a great host of Plaguebearers rose up from the mud and began to chant in a droning monotone as they came forward.
The seers channelled their psychic energy into great blasts of cleansing blue fire, boiling away huge chunks of Nurgle's army and darting out of the clumsy reach of their foes, but ever more Plaguebearers emerged from the slurry to block their path. The battle raged for days, and swathes of Nurgle's garden were blasted to ruin in the process. However, in the material dimension, the physical forms of the trespassing seers began to convulse and shake, succumbing to the very plague they hoped to overcome. Slowly, as their bodies shrivelled and their spirit stones turned to rotting mulch, the souls of the seers that were trapped in Nurgle's realm began to pass fully into the immaterium. The soupy atmosphere of the garden seeped into their lungs, worm-riddled mud spattered up their legs, and white-bodied daemonflies clambered into their mouths. Claimed at last, the seers' feet took root as their faces hardened into bark. Their arms split and twisted into gnarled branches, each finger hung with ripening Nurgling-fruit.
The seers of Lugganath remain there still, a copse of wailing trees that brighten Nurgle's leisurely walks and strike a note of despair into the heart of Isha, his immortal captive. Such is the fate of all those who enter uninvited into the heartlands of Nurgle, for even the generosity of Grandfather Plague has its limits.
"Hey guys, let's invade the realm of a Chaos God to rescue our captive goddess!"
"I just don't know what went wrong..."
