Except for Minerva.
Blue Lantern. Your de-aging abilities have gotten onto the internet, which is likely to prompt immediate kidnapping attempts. Multiple of me are flying to you as quickly as possible, as is Mirror. Who she can just ask, unlike Octavian, who has a chip on his shoulder rather larger than his actual shoulder and never answers her emails.
There are a significant number of supervillains who are likely to die of natural causes if they are not de-aged, and all of them have an interest in attempting to kidnap or suborn you. Not all of them are qualified but you can expect multiple attempts within the hour after I send this message.
And hopefully none of them will make it there too fast -
If you get this message, the safest place to be is
The Twentieth Century foundation building? No, a supervillain attack might total the anti-nuclear defenses she'd built into it, and then Chicago would be short a key defensive system if nuclear war occurred.
The AAS meeting room on -
and she'll give the address.
(It is chosen because Octavian sometimes hangs out over it and because there's nothing too vulnerable around it and because it has pretty good lines of fire for invisible robot armies, which are more likely to be her than her enemies)
As soon as you have finished your most important tasks.
Remember,
This is occurring because you are the hope of the salvation of the world,
Minerva.
Actually, if her Radiant-theory is correct, she should be summoning Radiant, not Mirror, but if her Radiant-theory is false than summoning Radiant would be disastrous, so let's go with the safe option, shall we?
