Isn't Force Stealth the technique Jacen taught to ben, who in turn taught it to hiw mother, Mara Jade?
That would be Force stealth (which I will cover). It allows a Force user to hide their alignment or even their presence from other Force users.
I am planning on doing Sith magic soon as well. Probably along with Darth Malak.
Edit: I do believe Force stealth is another one of Traya's powers.
I am also wondering about something, I gues you can call this my request, but are there other Force powers that control elements like fire? Streen could control the wind. Are there Jedi that can control fore, water and such?
I ask this because I write stories based on my old SWG characters and one I created for RP (not created in game but the baby of my Jedi) I gave the ability to control fire. Is it possible?
