It's said that the Shadow Isle's Black mist will kill someone when approaching near or on the Isles.....That means that Elise could have never got her spider powers without getting passed the mist.
And Evelynn......no words.
GreenLore3 votesAbout elise: Maybe the black rose actually has tools to protect them from the black mist? The new lore talks about a mystical veil protecting the blessed islands,so maybe that veil transformed into the black mist and can still be cleared away with the very same words that kalista used to get to the islands?
Alternatively it is possible that the black mist has its up and down times. After the harrowing it might disappear for a few weeks/months/whatever completely until it regenerated its power.Karthus merely arrived at a time where the black mist was powerful enough to manifest again.
FurriesAreHot1 votesWasn't evelynn born in the shadow isles? And didn't Elise have her powers before that, and just worships the vilemaw?
GenoXx1 votesWe know nothing about Eve, and no. Elise got her powers from Vilemaw. It's stated in her lore...
My concern is that Riot just made another loop hole. As it would seem impossible for the Black Rose team to go revive Sion or Elise going there. The black mist kills any living thing that gets near.....
So how did they even come back alive?
FurriesAreHot1 votesConsidering riot fucked up the LoL to not exist in the lore, It makes sense they fucked this up. Also I'm not up to date with my Shadow Isles lore
LaoBushido1 votespeople have made it on the shadow isle with out dying so it is possible to get there unharmed, also the black mist does not kill people the spirits with do we know that normal weapons can not affaect them but swain and leboc have strong magic
Trylobyte1 votesElise's connection with Vilemaw might give her immunity to the Mist. As for Evelynn, we don't know anything about her anyway other than she dated Twisted Fate.
GenoXx1 votesBut that doesnt make sense. For Elise to even meet Vilemaw...she has to get through the mist....and that isn't likely to happen.
Ralanr2 votesWell...how old is Elise?
FurriesAreHot2 votesMaybe from dating TF Lady Luck smiled

What? Where?
Then, the "job" of 
would be pointless.
I mean, look at this video: https://youtu.be/s2FFGBPXNeU?t=73
The guy does not die intermediately.
