My Conspiracy's about Kalista (Lore-wise)
Based on my limited knowledge of the League Lore I believe that Kalista may be the Ruined King's daughter. If I'm not mistaken the fall of the Shadow Isles was initiated by death of the princess by the hand of Mordekaiser (an act of Betrayal as he was the King's right hand). If this is true then the princesses spectre would most definitely be after vengeance and would explain the Red post in the Q&A about how she was there when all the problems in the Shadow Isles began.
Again this is all just my ramblings, what are your thoughts community? Also I apologize if I got something completely wrong and please correct me if I did.
