I have a fairly straightforward couple of questions here:

Is there any reliable, accurate literature about the fall of the Wendish temple fortress at Arkona to Archbishop Absalon's forces? I don't have any preferences on length, dryness, or entertainment value, I just want to know if anything reliably accurate has ever been published.

My second question is I want to know if there's any good reading about Absalon himself? All I can really find is information stating he lived, his name was Absolon, and he killed some Wends. This second question is also second in importance, it's just that my searching has made me super curious about him due to the lack of info I can find on him.
