Force-users Unite to Stop GAIT

"My fellow Force-users, my name is Kalja Sairu Leidias. Who or what I am is not important. All that matters is the message I’m delivering to you. The Force is dying. An evil entity known as GAIT is trying to subvert it to her will. If GAIT is not defeated, she will succeed in her goals. A man named Delth Ardin is fighting her on behalf of us all, but he can’t do it alone. He needs our help; the Force needs our help. Lend your power, all you need to do is will it to be so. It will be delivered to Delth and returned once GAIT is no more. This is our chance to give back to what has given us so many extraordinary abilities. It goes beyond Lightsider and Darksider. It affects us all."

- Kalja’s Call Across the Galaxy

The Uniting of the Force-users of the Galaxy occurred near the end of the Xen’Chi Invasion and would roughly coincide with the Battle of Chil’a’Chin to bring a permanent end to the conflict.

Jedi Master Kalja Sairu Leidias, using a ship known as the Mystic Aura, was able to send a message across the galaxy to every Force-user. The only way the message wasn’t heard was if the person had no sensitivity to the Force or was somehow blocked off from it. Otherwise, no amount of mental protection or ability to avoid detection was able to stop it since the power of the Aura essentially enabled the message to be one with the Force itself and not just a manipulation of it.

The call went across the galaxy, even to places and beings not yet discovered by the galaxy at large. The response was equally impressive, with the vast majority of the message’s recipients lending their power to stop GAIT. Most of the notable exceptions were Darksiders, but there were contributors even among them as well.

The Mystic Aura then acted as a conduit to channel all of this power into Imperial] agent [[Delth Ardin during his duel with GAIT. With it, Delth was able to finally put an end to GAIT’s menace once and for all. The Force was restored and the power that had been lent was returned to its owners.
