Lakna Rokee Shrine
You have to have first completed the Shrine Quest "The Stolen Heirloom" to unlock this Shrine. Learn how to complete it here.
Once you enter, there will be no puzzle since the trial was unlocking the Shrine and defeating the Yiga Blademaster. Grab the treasure chest containing the Edge of Duality, an ancient Sheikah weapon. Then go examine the veil and claim your Spirit Orb.
