What is "transia"

Transia (also Republic of Transia) is a fictional European country on the Earth of the Marvel Universe. It is one of several fictional countries in Eastern Europe created for Marvel Comics.

In nearly all story lines, the Republic of Transia is located between Romania and Serbia. More than 90% of its people live in one large town (East Transia) and a number of smaller villages located at the base of Mount Wundagore. The country is presented as mainly Slavic, with a Muslim minority in the western province Romani. President Russoff was a Secret Police Official in the communist era.

Within the Marvel Universe, Transia (and/or Mt. Wundagore) is where Chthon is imprisoned, and where the men of the Russoff line were afflicted with the curse of lycanthropy. It is used as the birthplace of Quicksilver and the Scarlet Witch. It is the base of operations for the High Evolutionary, and the source of the "radioactive clay" used by the Puppet Master.
