"I’d personally stopped him strangling two referees. However, I had no suspicion about what he was planning to do...."
-- Ivan Popa's testimony in the inquiry following the disaster (Pm)
Ivan Popa was a Quidditch player on the Romanian National Team (1809) and a holder of the International Wizarding Order of Merit.
With Romania losing, Nenad set off the forest in a rampaging attack known to history as the "Attack of the Killer Forest". Popa saved the day, later testifying that Nenad had been acting strangely for some time. He won International Wizarding Order of Merit for his efforts to save lives during the seven-hour battle with the trees (Pm).
Ivan is a form of John, deriving from the old Slavic name Іѡаннъ (Ioannu) and Hebrew יוֹחָנָן (Yochanan), meaning "Yahweh is gracious" (Behind the Name).
Popa is a common Romanian surname meaning "priest" or "pious person" (Ancestry).
