Initially, the Exiles are employed by the Timebroker to fix broken realities. The Tallus is a communications device, which is worn by the leader of the group in order to communicate with the Timebroker. Through it, he would assign missions to the team and inform them of any changes, etc. Blink wears the Tallus in the beginning, but it is later transferred to Sabretooth when Blink rebels against the Timebroker. Mimic also wears the Tallus for a time in Blink's absence. It is now used as a means of communication between its wearer and whomever is operating the Crystal Palace on various missions. It has a slightly different appearance for each wearer. For the first time ever, Sabertooth has used the Tallus to transport himself back to the Crystal Palace, without anyone on the other side recalling him.
