Go to the edge, use the bow and aim at the interactive wall visible in a distance. Create a rope bridge and get to the mentioned wall using it. Finish the climbing and start exploring new linear corridor. When you approach the main monastery entrance, the game will display an important cut-scene.
After regaining control over the main heroine, slightly turn left and position yourself at the new edge. Again use the rope arrow in order to create the rope bridge, aiming at the wall in front of you.
After sliding down the line, catch the interactive wall. Head to right and then to the next upper ledge. At the end bounce off the vertical wall in order to get inside monastery, thus reaching the location Chasm Stronghold (reward: 100 XP).
