Harmonia Vestige Part A
Location: Crown of Sand – Crown of Sand Entrance
From the mistle, follow the path forward heading down the ramp into the city ruins. At the bottom of the ramp, take a right following the street south. When you reach the end with a taxi next to a metal stairwell, take a right down an alleyway to find the vestige at the end on the ground near a dumpster.
Harmonia Vestige Part B
Location: Crown of Sand – Crown of Sand Entrance
From the mistle, follow the path forward heading down the ramp into the city ruins. Keep following the path straight over some sand until you come to a split. Take the left path to come to a dead end road with a traffic light. You will have to fight a tough enemy with red spikes here. After defeating the enemy, follow the path to reach a dead end where the vestige is laying on the ground near a corpse pierced with a bayonet.
Harmonia Vestige Part C
Location: Crown of Sand – Crown of Sand Entrance
From the mistle, follow the path forward heading down the ramp into the city ruins. At the bottom of the ramp, take a right following the street south. When you reach the end with a taxi next to a metal stairwell, take a left and follow the sidewalk. At the roadblock, take another left, passing over some sand (pictured above). This will bring you to a ladder. Take the ladder up and follow the path around a ruined building to locate the vestige on a ledge.
Harmonia Vestige Part D
Location: Crown of Sand – Sunken Ruins
From the mistle, head forward and climb the ladder to your right. This will bring you to a narrow alley where a lost will be hurling sand balls at you. Climb the alley using sprint/dodging and ducking into alcoves to avoid the balls. Defeat the lost at the top and follow the cliff to the left, watching out for the lost ambush. After defeating the enemies, head west over the sand to reach another path with an enemy in the middle of the path impaled by a bayonet. Keep heading west past this corpse into more sand. When you come to the split, take the left path into the alleyway (pictured above) with three spitter enemies at the end guarding the vestige.
Harmonia Vestige Part E
Location: Crown of Sand – Sunken Ruins
From Harmonia Vestige Part D, exit the alleyway and swing a left following the path towards the boss area. You will pass through a large sanded area with spiked slime and come to another split. Follow the path left (there will be a blue ladder on the right…pictured above) then take an immediate right (to avoid the dead end). The vestige will be located straight ahead at the end of the path guarded by an enemy (the path to the boss is at the end to the left).
