I Don't Understand Cassiopeia's Lore
So, the more I think about it, the more Cassiopeia's lore doesn't really seem to make any sense ever since it got switched to happening in Shurima, and it's starting to drive me nuts.
With her old lore, the origin of the curse was a Freljordian that she seduced into giving her secrets, and then betrayed. Her curse didn't really suit a Freljordian origin at all, but it made sense at least. Though the curse gave her power, whether it strengthened or weakened her didn't seem to be the point so much as it made her a monster on the outside that matched the treacherous worm on the inside. It was pretty much a petty revenge curse, and it worked for that, even if the origin was questionable.
With her new lore though, no matter how I look at it, the curse just does not make any sense at all. She received it from a trap that was protecting the Emperor's Tomb in Shurima, except that by any degree of logic, that is an incredibly shitty trap.
First, the fact that it didn't trigger on Nasus and Renekton when they stuffed Xerath in the tomb means the trap likely has to have been set up after Xerath was imprisoned. This means that, ideally, the purpose of the trap should be to prevent intruders from releasing Xerath and keep him imprisoned. Except that the trap doesn't even trigger until the tomb's been opened already, meaning it can not possibly succeed at this goal.
Second, since the curse now originates from an arbitrary snake-themed booby trap, it no longer functions as a punishment to specifically strip Cassiopeia of her beauty. Especially since her role as a seductress and her vanity played no role in that story. In fact, considering what we've seen of Shurima so far indicates that gaining animal traits is a high honour reserved for those who ascend, by the standards of the Shurimans who set up the trap, being aesthetically transformed into a half-human/half-snake probably wouldn't even be considered a disgrace. But then on top of that, the curse grants her all those poison-magic powers and... literally, how is she 'cursed'? How is that a punishment? By all standards, what's intended to be a trap seems to be nothing more than a free Ascension without the immortality bonus.
So, yeah, Cassiopeia's lore doesn't make sense to me anymore. Rito, explain please.
