What do you know.
Kz3r0 was right all along. Ei was the Baron's daughter.
So, the timeline looks as follows.
1888 - the Baron returns from Europe and orders the constructon of the mansion. (Why was the builder killed? Does it have to do with the Baron's work for the government?)
1889 - the Baron marries Tendou Shizune.
1891 - Shizune becomes pregnant with Mina and Eina. Shizuin moves in the Mansion. Yukina's mother is hired for help.
1900 - Shizune dies, supposedly in an accident (haha, as if). The Baron goes lethargic for a month, then goes mad.
1903? - people start disappearing, then the incident happens. Eina is about 12 years old when it does. Shizuin is a likely accomplice. (An attempt to get her sister back, similarly to Uehara?)
1908 - 'present' day.
I think the Elder is hiding the fact that they never found Eina among the corpses. She simply vanished. That, or he suspects something about the Tendou family (the circumstances behind Shizune's death or Shizuin's compliance).
It is highly interesting that Tendou girls always come in pairs. Is there some significance to that? Can't be a coincidence.
I am interested in the unholy alliance of Maedas, Tendous, Shinoharas, and now that we have learned it, Kimuras. There is some tangled web tying them together through the next century. So
C, I guess. Bonus points for being one topic he would be more knowledgeable about than the others.
Of all the options, only B, C and D make sense to me. The Elder who stayed clear of gaijins isn't likely to know much about the western rituals, and it would be best to ask the Tendou priest about the eastern ones. Pressing him for more information directly does not seem like a wise choice, though he seems civil enough that he won't throw us out even if we nag him.
Also,
treave.
She walks over to you and sits down formally, leaving you in the strange and somewhat uncomfortable situation of being flanked by two Maedas.
How being flanked by two Maedas could
possibly be uncomfortable?!
I almost want to reroll a character.
