Wind's prediction time! 

Chances for a good development: (Read: survival :p) (Joking. [i]Kind[/i] of.)

Lucien – 20-30%
Julian – 50%
Luciana – 60-90%
Solus – 60%
Mairyell – 90% (cuz he doesn’t give a shit)
Szayeis – 80%

Possible fates:

Lucien – gains or loses everything 
Julian – gets devoured / fixes or breaks the world
Luciana – regains sanity or goes totally nuts 
Solus – gets a chance to shine / gets swept in by events
Mairyell – gets a chance to shine / gets swept in by events
Szayeis – gains or loses everything

(the rest of the characters are in the periphery of the main plot so I can't say what they'll do when it kicks in or how it'd affect them)
