Explanation
The Vandenreich are a group of evil Quincy. They are the survivors of the Quincy massacre all those years ago that the Soul Society. The leader of the Vandenreich plans on destroying the Soul Society, with the help of his top soulders. The Stern Ritter are the group of strongest Quincy that the leader controls. The Stern Ritter are the Captains of the Vandenreich you could say. Each Stern Ritter are given a letter of the alphabet. The letters start off with A,B,C,D,E,F. When one dies the next Stern Ritter will gain the letter G. The leader would not go though the process of finding new members to help if they were not planning something big. Behind the goal of destroying the Soul Society, something else hides. The only main difference on this forum is that the Shinigami have figured out how to negate the Stealing of Bankai.
Everyone is the Vandenreichs enemy, they conquire everything. They are kind enough to offer you a position in the Vandenreich if they capture you. If you refuse then they will not give it a second thought, you will die. Their power is far beyond that of the the first Quincies that appeared to help Ichigo in the series. They are evolved Quincies. The old leader of the Quincies refused to grow and increase their abilities. So the Quincy broke apart and enhanced there abilities. The Quincy Cross and Glove have changed. The evolution of Quincy: Letz stil has changed and evolved. It no longer requires you to lose your power after use. Its name has changed to fit it more now. Quincy: Vollstandig, this is what makes the Quincy so Dangerous. Though the process of making and evolving techniques many have been made. Blut, and Ransotengai for instance, both are high power Quincy techniques.
