I've actually returned! Just gotta get up to date with the goings on and stuff.
You didn't lose much. After you went out the only things worthy of note that happened are:
- Diana and Suparna running by and leaving the scene as fast as they came.
- Titanica arriving into the battle by the underground lake/sea/whatever.
- Zeruel and Titanica going big and fighting one another.
- Henry getting a mecha of his own and going big to match them, in order to avenge the loss of his sword to Zeruel.
- Miyu buffing Henry's mecha.
- Khaine dropping the ceiling on people's heads.
- Suparna attempting (in vain) to spew some maggots on Titanica.
- And finally, Titanica doing an area nuke.
That's pretty much it up to
@thewizardguy's latest post, which I haven't read yet. The order may not be the same, but given the chaos around the battle, order matters little to nothing.
