Treachery walkthrough: sewers, Rivendare and the escape

The opening quest is The Sewers. Its requirements are exploration and the survival of both Garek and Landen. The dialogue tells the fighting group to lead while civilians remain behind.

1. Advance with both heroes and the surviving soldiers through the connected sewer passages. Clear the enemies blocking the group before moving the heroes into another room.
2. Use the minimap to keep track of explored corridors. The recording passes cell-lined rooms, a broad central channel and stair crossings before the exit checkpoint; the timestamped recording provides visual landmarks when similar corridors become confusing.
3. Keep an injured hero behind the fighting line and inspect available health supplies between encounters. This is Kingy’s recovery advice; the recording does not prove a required talent or equipment build.

At 21:32 the force approaches the guard near the exit stairs. At 22:02 the game marks The Sewers complete. Landen then gathers the survivors and leaves them with a soldier.

1. Continue through the sewer route until you reach the guard at the stairs and the completion message appears. Reaching an earlier cell or stairway is not the same checkpoint.
2. Let the evacuation conversation finish. Check the quest log for The Rot Within before leaving the area.
3. Regroup and review both heroes’ health and supplies. The next stretch follows the two heroes beyond the civilian handoff.

At 22:52 the new quest names Rivendare as the target and still requires both heroes to survive. The recorded route continues through a lower passage, cave creatures and a chamber strewn with bones before the confrontation.

1. Take Garek and Landen along the passage beyond the handoff. Clear the creatures along the cave route instead of leaving one hero behind in combat.
2. Use the cave section at 24:37 and the chamber at 26:22 as visual checkpoints. Continue toward the iron gate beyond the chamber.
3. Follow the encounter and allow its story sequence to finish. When the quest changes, follow the new requirement in the next section; the earlier target is no longer the instruction for the escape.

The ending changes to The Final Order. At 28:21, only Garek is under player control and the objective requires getting him to safety. The loss of Landen during this scripted sequence is part of the recorded progression; this guide does not establish an alternate rescue outcome.

1. Move Garek along the escape passage. Keep him moving toward safety rather than returning to the previous confrontation.
2. When Garek calls out the support pillars, break them to put debris in the pursuer’s path. The instruction appears at 28:36; the cave and debris checkpoint follows at 28:56.
3. Continue through the cave and sewer route with Garek alive. Use available health supplies if needed and avoid stopping for an extended fight during the escape.
4. Reach the outside guard and let the ending conversation finish. The recording shows the reunion at 30:11. Continue to Siege when the game offers the next chapter.
