I really hope the green mist is a teaser to the new marksman!

It 99% is Senna

Well lets see...

• The new champion is a marksman. Senna used a gun, which is now wielded by Lucian.

• First teaser shows light piercing through darkness. Senna and Lucian's guns fire something similar.

• The leaked image shows a black woman with a massive cannon. It would make sense for Senna to seek out a weapon she is familiar with.

• The black mist is blatantly obvious. We all know what it means.

• The new story featuring Lucian and Thresh, Homebound.

• The apparently leaked mission from Chinese test servers where Senna is apparently mentioned.

There may be more stuff I'm missing, but Homebound is especially no coincidence IMO.

Its senna. lol

if its Senna. god that is weak as fuck unless done in a good way. I mean very VERY good way

Unlucky.... :/
