Petras was an ancient city.
Founded "thousands of years" before 1965, Petras, carved directly into the rock of a mountain, was a young city ruled by the enthusiastic Prince Petra when nearby tyrant Salamander the Great, of Salamander City, threatened to invade Petras to satisfy the whim he had to issue commemorative pennies for a military victory of his.
Salamander's design was originally successful until history was unwittingly changed by Scrooge McDuck and Donald Duck, averting the Battle of Petras and leaving Petras to eventually celebrate its 100th anniversary, ironically issuing a 100-Year Penny to celebrate it.
Interestingly, Petras seemed to be solely inhabited by an ethnicity of sharp-beaked anthropomorphic birds, as opposed to Salamander City, exclusively home to anthropomorphic dogs.
Behind the scenesEdit
Petras is a major setting in the 1965 comic story Battle of Petras.
It appears to be loosely based on the notorious historical city of Petra, whose earliest point of historical relevance was indeed an unsuccessful attempt by a Greek city to conquer it. Although that city in question was not any variation of Salamander City as such, the assault was led by Antigonus I, the father of Alexander the Great, for whom Salamander the Great is named.
