Force call was a powerful Force technique utilized by only the strongest of Force-sensitives, due to the amount of energy required to use this power.
Utilizing the Force, a Jedi could call other Jedi to his or her position; this amounted to a shout that echoed throughout the Force itself. For those who heard this summons, it would be nearly impossible to resist. Raynar Thul used this to summon the survivors of the Myrkr strike team at the beginning of the Dark Nest Crisis, while Luke Skywalker used this technique on Ossus for a Convocation of the New Jedi Order shortly before the end of the war.
