Blade Drifts of Zopheir

The Blade Drifts of Zopheir (ゾフェル氷刃海) is an area in Tales of Vesperia located in northeastern Illycia, east of Capua Nor and north of Halure. At first, the area is inaccessible because it is too warm, but after Ehmead Hill is obliterated, this area becomes open to Yuri Lowell and his companions as an alternative path to Halure.

Karol and the Baitojoh
After Yuri and his friends failed to save Estelle from the clutches of Alexei Dionia, they crash near Capua Nor and notice a large crater where Ehmead Hill once stood. Once there, they find Teagle and his family at the inn and are informed that it is the time of year that the Blade Drifts of Zopheir are at the coldest, so the ice is stable enough to walk on. After thanking Teagle, Yuri and his friends press forward to save Estelle. Upon arriving at the Blade Drifts, they see many swords sticking out of the ice.

Soon, they are stalked by a monster known as "Baitojoh". They arrive at a crystallized are krene, became trapped in the aer flow, and are cornered by the Baitojoh. Yuri manages to push Karol Capel out of the way, but this forces Karol into battle with the beast alone. Things seemed hopeless until Karol pulls out a sword that controls the aer, freeing the others so they can join him in defeating the Baitojoh. After the battle, Karol is so exhausted from the fight that he passes out, so Yuri and the others fight their way out without him. Near the end of the dungeon, Karol wakes up as the group heads on out.

The Birth of Undine
After receiving Belius's apatheia from Don Whitehorse's grandson, Harry, Yuri and his friends return to the Blade Drifts with Estelle in order to put Rita Mordio's plan into action. They head to the aer krene and utilize it to create a substance known as mana in order to free Estelle from her power as the Child of the Full Moon. The plan works all too well, as the apatheia's formula begins to rewrite itself and takes on the form of a beautiful woman. When she first speaks, Judith recognizes her voice, and the others come to the conclusion that Belius's consciousness resided within the apatheia. Yuri gives her a new name for her form: a Spirit, and it is Estelle who officially names her "Undine", after the ancient ruler of the waters. Upon leaving, Yuri and his friends notice the threat of the Adephagos is growing stronger and they do not have much time. They leave to find more Entelexeia to turn into Spirits.
