Here's a CBR article that detailed what happened in The Forge:
So yes, Batman kept the Anti-Monitor's tower from Crisis.
Dark Days: The Forge lived up to itís name by revealing, oh, about thirty different proverbial irons DC Comics has been keeping in the fire. With a cascade of new information and returning faces, the road map for the highly anticipated Scott Snyder and Greg Capullo helmed Dark Nights: Metal is starting to make itself more and more clear.
But more importantly, though Snyder is on record that Metal is not a capital-C Crisis, itís more obvious than ever that itís going to be on the same scale as those sorts of DC events.
Letís take a look at what we know, and what it all means.
PLAYING IN TUNE
With the help of Scott Free (making a major return just in time for his Tom King and Mitch Gerads-helmed solo series, no doubt) Batman is able to recover an item heís, apparently, been keeping stored away deep within the vaults of Supermanís Fortress of Solitude.
The ďitemĒ is actually a giant golden tower that may or may not look familiar to long time DC readers as a ďcosmic tuning forkĒ straight off the pages of Crisis on Infinite Earths.
Donít worry, if you found yourself scratching your head at that reveal, youíre most certainly not alone. Itís been over a decade since weíve seen anything like it.
Hereís the Cliff Notes version of what it is, and where it comes from:
As part of the original Monitorís plan to ďreconcileĒ the multiverse that was being eaten away by anti-matter he placed these tuning forks across multiple Earths and sent heroes to go defend them from anti-matter shadow demons. The Monitorís theory here was that these tuning forks would allow him to align the vibrational patterns of these disparate Earths and save them from the encroaching nothingness that threatened them.

Much later, during Infinite Crisis, one of these tuning forks would make a reappearance, this time combined with another Crisis on Infinite Earths holdover, the corpse of the Anti-Monitor. In this event, Alexander Luthor, Jr. (a hero from Earth-3) planned on using the power of the tuning fork and the Anti-Monitor to resurrect some of the Earths that had been erased out of the Multiverse back in the original Crisis.
You might be recognizing a reoccurring theme here. Every time one of these golden pylons ends up in play, the stakes are almost immediately elevated to cosmic status.
And with cosmic stakes on the table, a Crisis-level event canít be too far away.
Of course, weíre left with some questions about just how Batman got his hands on the tuning fork in the first place, or where it may have came from ó whether itís a relic from the Monitor or Alexander Luthor, or somehow, neither. But as Mr. Miracle advises, regardless of where the tuning for came from, itís absolutely dangerous, and probably better left alone.
Which, of course, means Batman is going to continue to experiment with it.
