Will Soraka's lore also be changed with Warwick's rework?

I hope so, though there's no guarantees here.

Of course it depends on whether changes are actually needed or whether Soraka's current lore can still work as a stand in. As a reminder for folks nothing in Soraka's bio actually hints towards Warwick's motivations, only that he's a right royal bastard. it also doesn't speak to what he did following this event. Soraka's lore might not need updating depending on what Warwick's new lore is like. As long as Warwick's lore doesn't directly contradict anything about Soraka's lore things should be fine, and the thing is that all that has to be done here is say Warwick went to Ionia and caused suffering for folks over there. It doesn't need to mention the invasion, or any individual in particular, not even Soraka, just leaving that open would be enough to ensure Soraka wouldn't need an update for the time being.

So yeah, it depends.

Woah, woah, woah. Singed's, Warwick's, and Soraka's lores all synced up? No, that just wouldn't be right. Soraka's lore can't get an update until afterwards, and that update has to invalidate something in Singed's or Warwick's lore.

I just hope Warwick will still be linked to Soraka!
