Funny, that -- I was just looking over Tauroneo's business the other day for unrelated reasons. He tells a wonderful story, though.

Worth noting that the fallout between Lehran and Altina is central to FE10's plot. That one's pretty complex too, mostly for what made Lehran take things upon himself the way he did.

There's also Ashnard/Almedha, albeit that was a relationship that never reached maturity, so to speak.
