Spleen. The spleen is an organ in the upper left abdomen, which filters blood, disposes of worn-out red blood cells, and provides a 'reserve supply' of blood. It contains both red tissue, and white lymphatic tissue. Different parts of the the spleen specialize in different kinds of immune cells. Lymphocytes initially develop in the bone marrow. 2  Some migrate to the thymus, where they mature into T cells; others mature in the bone marrow as B cells. 3  Neutrophils: are the most abundant type of white blood cells and are an important part of the innate immune system.

After the quest was Alduin's Wall was finished Delphine and Esbern stayed in Sky Haven Temple for as long as I stayed there. When I talked to Delphine immediatly after the quest I was able to start the quest Rebuilding the Blades. After I left Sky Haven Temple and returned I found out that Delphine and Esbern had left. Delphine went back to the Sleeping Giant Inn and Esbern went back to his place in the Ratway.
