The TKN ritual was explained at the Centennial. It does not resemble to AM ceremony much. There is a TKN robe on display at Indy and should you visit they will make a TKN ritual book available to you to read.
Part of the merger deal was that the TKN ritual would never be performed and we've kept that promise.
Good to know, hope to make a pilgrimage to Indy sometime soon.
