First of all, thank you for this opportunity to answer the community's questions!
I have been wondering... since LWS4 Episode 1, "The Hero of Istan" shows that Revenant Players in their cell could invoke Joko's power, despite Joko showing up later in said episode ... is it necessary for the legend a revenant is trying to invoke to be dead? (which is the case with most legends the player uses)
Or can they also channel still-living legends that have left "their mark on the mists" before? (see Joko in that episode)
Or does Joko in particular not anide to the laws of "dead" or "alive" since he's a lich?
OR was Joko in this episode's case just a small joke without any lore significance and I am interpreting too much into it all?
On that note: if a legend is invoked and they start interacting with their revenant, are we talking to the legend at the point in time they placed their mark on the world, or to the legend after it has died?
