Well, since everyone is all hung up about my OTP…

Yes, Sorin created Avacyn, but that doesn’t mean that he adopted her as a child. He didn’t raise her, he didn’t have time to, and he didn’t create her just so he could have a child. She is a powerful angel created to protect the humans of Innistrad while he tried to calm his brethren (the vampires) and establish peace on his plain.

They were a team, not father and daughter.

There is a bond, yes, because he was passionate enough about protecting his people to create an angel like Avacyn, and he does speak of her possessively - “Avacyn, my angel, what has befallen you?”, but that doesn’t mean that shipping Avacyn and Sorin is incest.

(opinions incoming) Avacyn was a creation, and therefore created for a purpose. Hers is to protect, and her main priority is to do just that. She doesn’t call Sorin “Dad” nor does she strive for any sort of emotional ties between other beings. All she must do is do whatever it takes to protect Innistrad, along side Sorin.

A creation is not a child. And I don’t believe that Sorin would see her as such either. She is his angel, a being he made that is more powerful than he. Calling her his child would be an insult, suggesting that she is helpless and that, at the end of the day, she would need Sorin to make the hardships all better.

Therefore, the tides of this could easily switch towards romance when she was locked in the Helvault and had no idea where she was.

/end rant.

What Are Silvan Elves?

Alright, everyone ready for an elvish history lesson? In the beginning, while the elves were traveling west for Valinor, there were three Sunderings (almost everything elvish comes in threes.) The First Sundering was when the Avari refused to follow the Valar, and instead remained behind in Cuivienen. The Second Sundering was when some of the Telerin elves refused to cross the Misty Mountains, and broke off from the rest of the elves. This group became known as the Nandor, and they mostly settled in Greenwood/Mirkwood. And the Third Sundering came when some more of the Teleri refused to cross the ocean, and remained in Beleriand, becoming the Sindar.

Later during the First Age some of the Nandor traveled west to Beleriand and settled in Ossiriand, and throughout the age many of the Avarin elves joined the Nandor living in Greenwood. So, by the time we reach the Second Age, the elves still living in Greenwood (as well as Lorien, and in the southern haven of Edhellond, near Dol Amroth) are referred to as the Silvan elves. They’re basically just the descendants of the Nandor, with some Avarin influence. And then, later, when the Sindarin dynasties are established in Greenwood and Lorien, a Sindarin influence is added to the mix (as well as some Noldorin influence in Lorien.)

The Silvan elves are interesting, because while there are many examples of multi-cultural elvish settlements and communities, the Silvan elves are the only ones where the diversity and intermingling was so great that Tolkien actually renames them. But the main influence would have been Nandorin.

A (Super Brief) Outline of Elvish Linguistic History

So, actually, Sindarin didn’t come from Quenya at all - the two languages share a common root in Common Eldarin, but each come from a separate branch of the languages that developed from that language.

Probably the best example of the differences between the elvish languages (or, at least, the most-developed of these languages), is the word for “elves.” In Primitive Quendian the elves called themselves the “kwendî” (sing “kwende”.) Tolkien then lists six different Avarin words for elves, theoretically representing six different Avarin languages (“kindi”, “cuind”, “hwenti”, “windan”, “kinn”, and “penni.”) A Common Eldarin equivalent isn’t listed, but the “modern” Quenya word used is “quendi” (sing “quendë”), and the Common Telerin word is “pendi” (no singular.) And Tolkien says that there actually isn’t really a Sindarin equivalent for this word (there isn’t even have a Sindarin word for the Sindar.) However, the Sindarin word for person, “pen”, is clearly taken from the Telerin “pendi.”

I’ve seriously simplified this topic - Tolkien wrote several linguistic essays about Middle Earth, especially the elvish languages. The chart above is, again, very simplified, and I’ve left out many dialects for the sake of sticking to the basic point that Quenya and Sindarin are linguistic cousins, not parent and child.
