At least a few tidbit of lore from the Blizzcon (the novel...snippets) heavily indicates that compared to the aftermath of the Lich King return (WOTLK), or the Cataclysm (Duh), optimism is in short supply and there is a couple of allusion to ''a dying world''
Heavily featured in the latest lore is the fact that Titans are the literal avatars of worlds, the ''souls'' of those worlds. With all Titans dead and/or turned evil, the future of Titans is related to the two last known ''Titan wombs'' worlds, Azeroth and Argus.
Now, I can't help to notice that the Titans are dangerously vague about what exactly happens when a ''womb'' world give birth to a Titan, but to be blunt, did Sargeras did some sort of planetary c-section on ''soul'' of Azeroth, thus leading to the world dying ?
(I might have a too perverse mind, but I'm not above thinking that the ''wound'' in Silithus might be, y'know, with the shape, the...origin...of the Azeroth titan ?)
