Seems like they're preparing a new part of Time Temple.

Finally someone with a bit of common sense. Does anyone knows when the new KMST patch is coming? Or even if the Demon Slayers quests hints to the new boss? And isn't the storyline of Pink Bean of only 1 hodded man that enter by force to Temple of Time, and tried to bring back the Black Mage, but since he was too powerful (Black Mage) brought the Bean back? And I BELIEVE the new door will be a travel to the past, it should be, I will be dissapointed if not. But oh well, who has info that isn't sharing?

Now that you mention that... That hooded guy, could it be the "snake guy" from behind? It'd make quite a lot of sense.
