Brother Arkel, a Devastator, once of the 9th company stayed behind to ponder over the concerns of his Chapter Master. He looked upon the maps of Targon and sought a location that would be deemed fit enough for their new Fortress. The North proved cold and harsh, a fine location to train young warriors. The South was cropland, a place where the more noble aspects of community and decency that the Blood Angels pride may be found. And there, to the East, he saw the sprawling deserts of Targon.
The Blood Angels knew the tenacity and survivability of those who lived in the deserts from their own childhoods. While he assumed the deserts would not be like the wastelands of Baal, the Blood Angels would be more familiar with what sorts of trials and rituals could be conducted in such a place. He would suggest that there might be the best location for the new chapter's home, not just because of this, but because it would also feel more like 'home' to them. It had been some time since he himself had set foot on Baal, and it may be unlikely that most of them would visit their home planet again. To be back in the sands may prove good for them all, and may make it easier for them to bond with the Targonian people.
If the Chapter Master feels his view is too sentimental, he would suggest somewhere nestled in the mountains, with a small base at the foot of them to communicate with those of the croplands and farms. The North would prove strong and tough warriors, but it would be unwise to turn away those who are skilled at growth and nurturing, especially when the chapter itself is in the cradle of creation.
