[Warning: Possible spoilers ahead! -- sorry, Arturis!] The shaping-up-to-be-über-sweet Patch 2.4 has a few more surprises stored in its files. Some folks were able to dig up the model for a unique-looking demon boss named Entropius. While no more raid bosses have been announced -- it's just M'uru and Kil'jaeden left to kill in Sunwell Plateau on the PTR -- there is much speculation as to the relationship between the formerly chained-up, payback-seeking M'uru and this so-called "Void God". Entered into the wowhead database as early as February 13, it looks like this anorexic voidwalker has more in common with the Dark Naaru than originally thought.
The folks at MMO Champion certainly seem to speculate that M'uru and Entropius are pretty much one and the same, or at least that Entropius is pretty much tied into one of the rumored phases that the M'uru fight will have. You can check out the images above to see them superimposed over each other. See something familiar? It looks like Entropius and M'uru go to the same haberdashers for their shoulder gear. Lore fiends are debating on their relationship now, but in the meantime, it's really nice to see that Patch 2.4 isn't just bringing changes to items and game mechanics, it also seems to promise a lot of developments to World of Warcraft lore.
