..those names...are they from Dishonored? I know Daud was the assassin who killed the empress. Dunno any Delilah though.

Yep!

Delilah is from the DLCs Knife of Dunwall and Brigmore Witches. She's basically the main antagonist for both of those, and is a witch who wants to transfer her soul into Emily Kaldwin to become empress.

She also has the mark of the Outsider, which explains her powers.
