With the redactor, one can execute slipshank operations by sending messages into the past.
What does this mean? When someone in the present wants to have an object or an information at location X right now, he can travel in the future with a time machine into the past. In the past, he can place the desired object or information at location X so that it will be available there in the present. Problem solved.
Alternatively, in the present he may send a message to his former self in the past by using Chronotech. By this message, he is requesting himself to place the object or information at location X in the past. Problem solved? No…because obviously, the player does not know about this request in the past. One can simply say that in this case, the character knows more than the player. But if the player should know everything the character knows, clearly causality has been violated, because in the past neither player nor character where aware of a message which has arrived from the future. But if the mind redactor automatically erases the memory of the character after he has fulfilled the request from the future, both he and the player do not know anything about the request. Thus, causality is saved ;)
There are possibilities to execute slipshank operations by sending messages into the past without the need of mind redaction. First, if the character is part of a group mind and this group mind is not sharing all thoughts between its members and at least some members of the group mind have chronotech available.
Or the character is asking the Transcendentals to send the request into the past to someone else. Or in the simplest case, one can order slipshank operation messages to be sent from a service provider :)
