No, you really don't need to consider it. It's the Skyrim Lethiel who is not part of any of my storyverses. She only exists--so far--in the context of the game.

That does not apply to our Lethiel, who obviously ispart of the storyverse on which we worked together, and may show up in others. You've been writing about her

They're two separate characters who--unfortunately, it seems--have the same first name, because I liked it. Sorry to cause confusion.
