So what we learned from the Harrowing chapters
In no particular order...
Hecarim, the shadow of war, used to be an actual man Olaf wanted to die a glorious death and become a fucking legend ("Did that beast just shit you out?") Miss Fortune wants to take back control of Bilgewater (after surviving the Harrowing) Rafen's an awesome dude Lucian still grieves to this day for Senna (not sure if learned but reiterated) Lucian learned Senna wasn't killed, she was captured Illaoi worships this Nagakabourous Illaoi doesn't like the dead coming back The black mist claims your soul and you become trapped in it Hecarim is the leader of these souls (feel free to add on anything else)
Note: I have not actually read any of their lore. This is just what I got from the story lol.
Wait.....I just realized, where does Karthus tie in to all of this? Why was he not part of the Harrowing? The master of death should totally have a chance to be in the Harrowing. When does Karthus come? Q_Q
