I think, the romance part is more a construct by that fanfiction writing druid, but the rest is pretty interesting. Tbh - the part in the video about
the Nightsong and how she came to be (btw, awful armor, but nice hair) made me think, that the same could have happened to Shadowheart. So I'm not sure about the whole Halsin helping to hunt Cazador part, but I'm pretty sure, we will find out, that Ketheric had brainwashed SH to become a Shar worshipper - that seems to be his style. And that would explain, why she isn't evil enough for a real Shar worshipper.
Btw: I did read that fanfiction, I think, it was in Netties room, but I totally forgot about it.
