Árheimar

Árheimar (Old Norse "river home") was a capital of the Goths, according to the Hervarar saga. The saga states that it was located at Danparstaðir ("Dnieper stead"), which is identified with the ruins of Kamjans'ke Horodyšče, near Kamianka-Dniprovska in southern Ukraine.

Hervarar saga
The name first appears in the Hervarar saga when Angantyr has avenged his father Heidrek and retaken the Dwarf-cursed sword Tyrfing:

"And when it was close on midnight, Angantyr went up to them and pulled them down the tent on top of the slaves and slew all nine of them, and carried off the sword Tyrfing as a sign that he had avenged his father. He then went home and had a great funeral feast held to his father's memory on the banks of the Dnieper, at a place called Arheimar."

It was during this feast that Angantyr's Hunnish half-brother Hlöd appeared with a large army to demand half the inheritance:

The next place is when Angantyr's brave sister Hervor fights the Huns, although her small army is greatly outnumbered by the horde and she knows she cannot win:

""Then Ormar rode back to the fortress, and found Hervör and all her host armed and ready. They rode forthwith out of the fort with all their host against the Huns, and a great battle began between them. But the Hunnish host was far superior in numbers, so that Hervör's troops began to suffer heavy losses; and in the end Hervör fell, and a great part of her army round about her. And when Ormar saw her fall, he fled with all those who still survived. Ormar rode day and night as fast as he could to King Angantyr in Arheimar. The Huns then proceeded to ravage and burn throughout the land."."

Arheimar is mentioned for the last time when the Geatish king Gizur arrives with his army from Scandinavia to fight for the Goths, and tells the Huns where the Geats and the Goths will meet the Huns in battle. Hlöd demeans Gizur by calling him an Ostrogoth (Gryting) and 'Angantyr's man from Arheimar', and not a king of the Geats:
