Tel-Shan
This world is unusual for the Oestalan Sector. It is a verdant paradise, shielded from the ravages of the Great Storm by means unknown. Nothing lives here but plants of every type and description; their diversity is as astounding as it may be lucrative. A handful of Genetors operating in advance of the Oestalan Crusade have arrived on the planet, and are busy rendering down everything they can get their mechadendrites on in the search for useful chemicals or genetic strands.
The Ecclesiarchy has petitioned to have the world dedicated to their use as a holy site (and a wonderful vacation home for the high rankers), and the Administratum likewise wants it as a Pleasure World for their people. Both want the Genetors off the planet before they chop down everything that makes Tel-Shan habitable and pleasant.
The political debate rages on, and is beginning to grow quite heated. If someone doesn't act soon, there may be outright conflict in short order.
What few know is that Tel-Shan is a Maiden World, seeded by a Craftworld now lost to the Great Storm. They landed their massive ship to ride out the storm, and over more than a thousand years of raging Chaos, the entire Craftworld became buried in hundreds of years of growth, decay, and eventually dirt.
The Craftworlders are just now emerging from their impromptu bunker, and though they are planetbound, they will defend the world to the death if need be, for it has finally aged to the point where they could at last have a true home after so many years.
