How to unlock the "Legacy of Hanu" achievement in Honkai: Star Rail

Open the Hour of Fire: Fire event platform

The Fire Hour: Fire event can be unlocked in two ways:

• During the main story mission “In our time”, namely after the “Favorite” stage;
• By starting the side mission "Rest in the Scorched Sands", which will provide access to the remaining sites that were not previously selected.

Regardless of whether you got here through the story or discovered later in the adventure quest, you will still be able to get to the puzzle that rewards the achievement.

Go to the Mosaic of Dreams

To get the hidden achievement, you will have to move around the floors, from time to time changing appearance between a squad member and a wolf gnome. The main task is to open the way to a spatial picture, through which you can get into a closed room on the eastern half of the 2nd floor.

From the anchor in the south of the mansion, move straight through the passage leading to the first floor hall (if the door is not opened with the key on the back side, activate the Hanu Adventure machine and crawl through the gnome door). Then go up the stairs to the second floor.

Check the elevator on the first floor - if there isn't one, call it to that level so it doesn't block the painting on the second floor.

On the second floor, go into Hanunu's office and take on the appearance of a gnome to go into the next room.

Climb into the room with Hanu's test on the second floor and immediately run to the machine in the corridor leading to the exit from the map to return to your normal height. Return to the hall again and go to the passage painting (it is located behind the elevator shaft and should not be blocked unless you forgot to drive the elevator to the first floor). The teleport will take you to a closed room with another door for the gnome.

Open the room from the inside and again go to the transforming console in the nearest corridor - here we again change with Hanu and return to the very door that was in the previously opened room. This way we will get to the platform above the 2nd floor: all that remains is to go to the control panel and return to normal height.

All that remains is to assemble the Mosaic of Dreams: use our hint, on which we marked the parts with the same colors and their correct location (if it doesn’t fit, rotate the element).

If you correctly assemble the puzzle picture, three chests will appear in the hall under our current location: two ordinary and one luxurious. When you open the central, most valuable trophy, you will be given the “Legacy of Khan” achievement, for which you can additionally receive 5 jade.
