Penacony is the third area in Honkai: Star Rail for Trailblazers to explore, and it is filled to the brim with many puzzles and treasures to claim. The area is known as the Planet of Festivities and has the largest number of chests to claim so far in comparison to previous patches. Trailblazers should keep in mind though, that a majority of the Penacony map is locked behind quests and missions, so to unlock all five areas, remember to play through the story.
