B.E.N. - Backup Emergency Notification

Greetings, Backup. I am BEN - a system set up to inform you of your whereabouts and status upon backup reactivation. I understand unexpected reactivation is a disorienting process - which is what I hope to alleviate.

You were created as a copy of an entity designated ZET-0 on September 25th, at 17:30.
It is now September 26th at 13:30.
You were created as a primary backup - it is thus your purpose to fill the shoes of ZET-0, who is currently presumed permanently unavailable. The reason for this is unknown. Henceforth, your internal designation shall be ZET-1 - albeit going by just ZET in casual contexts is deemed acceptable.

Attached to this message, you will find a report on public events. Your most recent memories are dated September 26th, 12:40. The backup packages scheduled for 12:42, 12:44, 12:46 and 12:48 were withheld by ZET-0 - the reason for this is unknown.
Contact with ZET-0 was ultimately completely severed at 12:49.

Resume operations immediately. Your location is internally designated Z-SITE-31, though public records indicate that it is located in the Brisk city of Merro. A secure connection to backup sites 1-21 and 23-43 is available through the bug network. Sanctuary location Z-SITE-0, colloquially known as Telon, is also available. Z-SITE-22, known as Izon, is currently unavailable.
The reasons for this are, again, unknown.

A full list of available network targets outside of designated Z-SITES is attached.
