Alright. So you are one of 26 Blood Angels (and one Flesh Tearer, Brother Librarian Arbun) sent in this new founding to the Targon System on the only habitable world of Targon Prime. The planet has one small fortress that was more the ceremonial residence that, with the handover of the system to us, is now ours. The former Planetary Governor is now one of our attendants, he commands the PDF under us.
On our new homeworld has a single large continent. The north is mostly snowy mountains. The people here make food through hunting, trade and light mining.
In the far east is a small desert, roughly the size of Australia, inhabited by a mix of nomadic herders, fishermen and some permanent settlements. While they are ethnically the same as the rest of the planet they are a bit different culturally. This area is notably a lot like Baal. But with less radiation.
The south, west and central area is a mix of forested areas and planes that are used for cultivating fields or grazing cattle.
Several years ago we had a battle with the Blood Ravens chapter as they attempted to plunder our relics on our homeworld. In the end, we killed them all, "sunk" their strike cruiser and went over the the contents of what we could salvage.
