The final issue of a mini-series that bridged (I think) the New 52 and the Rebirth versions of the Green Lantern Corps, EDGE OF OBLIVION was a tale of the GLC getting back to their home universe after being stranded in some other/earlier universe following the events of GREEN LANTERN: THE LOST ARMY.
Finding a single planet with one remaining city, the GLC are then suckered by some tall, good looking gods who claim to want to save the city and its planet. The GLC led by John Stewart and Guy Gardner realise too late that the gods are monsters looking to find a way into our universe and begin feasting – because what else do these sort of creatures do?
Multiple Green Lanterns are killed but as we’ve never met these ones before, their loss is used to illustrate the scale of the issue rather than to elicit an emotional response, plus as they die, their rings head off to find replacements and Simon Baz realises they must be sensing the GLC’s home universe. He tracks them to a rip in reality and follows them through.
The Corps move the city to Mogo and then push the aliens back to the planet which, like Mogo, is sentient.
With the planet trapping the monsters, the GLC (including Mogo and its new city) are able to reach the tear in reality and head through, disappearing into the unknown.
EDGE OF OBLIVION wasn’t a bad series – I remember enjoying it more than THE LOST ARMY that came before it – but am not sure it was ever mentioned again; I certainly don’t think the saved city on Mogo was ever revisited, though feel free to tell me I’m wrong.
It was nice, though, to see members of the GLC like Two Six, Iolande, and Graf Toren that haven’t been around much lately.
