How do you know he speak lakota? I listen to some of these people claiming to speak my language
and they are not speaking Lakota.
So this man is taught by fakes so he is a fake he does not speak for my people 
Earth, in one of his profiles Lahann claims he spoke Lakota. He also claims a 'good' knowledge of English, while I gained the impression that his abilities were, errm: modest. Well, it seems these are not the only things he's deluded about. In fact, in one of his profiles, he only lists 'German' as the language he can communicate in - no mention of English or Lakota or whatever.
He maintains profiles with Xing and LinkedIn, and in his Xing profile claims he speaks English, Spanish, and Lakota, while the LinkedIn profile only mentions English and Lakota.
The Xing profile also says Lahann is a member of "Wolfsklan" which was founded by one Matthias Walter who also goes by "Lightfire". Walter claims Larson Medicinehorse as his teacher and says Medicinehorse 'foresaw' the founding of this clan. Another claim Walter uses is that he was a messenger of Buffalo Calf Woman. I do not recall Lahann claiming membership in Wolfsklan from earlier research, so it is possible that he is a later addition to the outfit and may have received any 'training' by Walter.
@Sturmboe:
From what you describe, it seems Lahann is having mental issues and should seek professional help. He does not seem to be prepared to recognize he needs professional help, so nothing can be done until he becomes a danger to himself or to others.
However, in my research I also realised that there is not one single person who claims Lahann for their teacher, despite Lahann offering/ selling courses to make shame-ons. So apparently he appears weird enough he is not attracting clients, which is good news. I do see some results showing that Lahann maintains a few websites for a minor number of clients, and I also noted that other clients apparently switched to different services since the last time I researched Lahann. This is probably also due to his issues.
Over the years, I have researched some persons who - even judging only by their comments on websites and in advertisements - gave a very strong impression of being in need of professional help. Still most of them managed to draw customers, at least for some time, with a few clients constantly ignoring all warning signals.
Although this lecture done by Lahann certainly will have been an irritating experience to sit through, it seems that Lahann is so much off the rocker he's discouraging the audience from booking seminars and courses with him.
As I said before just from a mere glance at his different activities, he seems not to attract clients but rather to the contrary, and therefore he's grabbing for every straw in sight which might generate some income, inlcuding pyramid schemes.
