As was only common courtesy, Bruno was given a full tour of the Romanian King's estate, as well as a lengthy, albeit interesting, explanation of his family's history. The Kingdom of Romania was young, established as a kingdom as far back as 1881. But the family's house was naturally much older, being the Swabian Branch of the House of Hohenzollern, which now ruled over the German Reich.
Many people in his place might find such a lecture to be a dull affair, but not Bruno; he was quite an avid enjoyer of history. And naturally, such ancient houses possessed knowledge that one might say was more difficult to dig up through conventional means, either in this life or in his past life.
Either way, Bruno had more or less proved his interest to the Romanian King, both in terms of his family's history and his attempts to establish proper ties to them. Bruno was, after all, rather charming when he could be compelled to socialize.
