i just made this connection after playing against a 
as 
and seeing him just shit on my ult and ghouls as if they were nothing.
its a pretty cool how the game connects with lore like that.
I'm pretty sure Yorick's Mist Walkers won't attack Lucian.
I'm also pretty sure that it's a not-really-coincidental sort of coincidence, because both kind of spirits/undead/ghouls obviously have similarities due to them being cursed by the same curse, in the same place, but the ones in Lucian's splash weren't based off/inspired by Yorick's Mist Walkers (because Yorick's simply came much later). Just sayin'. :P
Those ghouls have eyes, though. Yorick's don't.
