Before the WarEdit
The exact origins of Terralain are unknown, though it is known for being inhabited by particularly large and powerful rabbits. It seems to have passed out of the knowledge of the rest of Natalia's inhabitants by the time of King Jupiter.
However, it was rediscovered by Prince Bleston and his band of malcontents after their departure from First Warren. By some means Bleston became the First Lord of Terralain, which became the staging ground for his eventual plans to seize the throne over all Natalia.
The land of Terrain is mentioned frequently in conversations with Kyle, the Second Lord of Terralain and its infiltrator in The Resistance. Kyle frequently makes claims as the the veracity of its existence, but is firmly countered by Emma.
