Inbox

"Coolcoolcool. Funfunfun."

Note: Abby does not keep herself connected to the Network as a habit. She has a mailbox on the edge of her domain for letters and messages she should contact someone from the other factions.

And in Cadens there's a box for slips of paper on her door in Sarstina.

In either case we can handwave to just giving Abby a time/date to be on the network for an inbox thread. Or a place to meet in person/on the horizon as you desire.
