In 1919 Pʻun-kʻaṅ taiji bKra-śis-rdo-rje was appointed kung ⁵, the only attempt by the Dalai-Lama to succede the defunct Chinese Ch’ing dynasty as fons honorum.
Consider the case of the Religious and Military Order of the Knights of the Holy Sepulchre, headed by Professor L.D. Worley, d/b/a HE the Count of Maxalla. HE does not claim that the “Order” descends directly from some medieval order. He candidly dates it from recent times (1987, IIRC.) On the other hand, he does claim a Fons, a certain Abbot-Bishop George, head of the Holy Protection Monastery in Geneva, Nebraska. This gentleman’s checkered career IIRC, began as a Pentecostal, and ended up in Copticism, with way stations at Hinduism and Gnosticism. Bogosity, thy name is Abbot-Bishop George. I suppose the question is whether HE actually _believes_ that “Orthodox Abbot-Bishops” are fontes honorum.
Guy Stair-Sainty’s website has a good, erudite section on fantasy royalty, but the pages don’t focus on the fraudulent activities for gain of such people, nor on title sellers who do not themselves pretend to be fontes honorum.
