Caelid
According to the Wikipedia, Caelid is A wasteland on the southeastern tip of the Lands Between, plagued by Scarlet Rot and inhabited by all manner of malformed creatures. Caelid was the site of the Battle of Aeonia between General Radahn and Malenia, Blade of Miquella, during which the first flower of Aeonia bloomed and covered the region in Scarlet Rot. Radahn's army, the Redmanes, continue to combat the rot using fire to this day. The region is lined by smoldering walls and dotted with colossal remains.

The Blighted Wastes of Caelid

Once a land of red earth and mighty fortresses,
Caelid was a vital stronghold in the early days of the Golden Order.
Its lords stood as fierce warriors, their banners flying high over the battle-scarred plains.
But when the Scarlet Rot took root, the land was cursed beyond salvation.
In the wake of the great battle between General Radahn and Malenia
Blade of Miquella, the once-proud region was left to fester.
The rot spread like wildfire, twisting the land into a wasteland of decay,
where the sky burns crimson and death lingers in the air.
