Rozrog or Rosrok is a fortress in Verden, a kingdom which borders Cintra. The fortified city is at the mouth of the mighty Yaruga. Nearby are the fortresses of Bodrog and Nastrog. The Yaruga river itself forms a natural border with neighbouring Cintra.
Rozrog stands as the legacy of actions taken by the elves during the Time of Contempt.
In the Something ends, Something begins non-canon short story
The castle apparently now the property of a certain former king Herwig, serves as the setting for Geralt and Yennefer's wedding. Galahad mistakes the ruins for Montsalvat, but Dandelion asserts that they are not in Avalon, but Schwemmland, which translates roughly to "marshes".
It is described as a shapeless heap of stones in a dire need of general repair, standing on a cape in the middle of the lake.
Rozrog is mentioned as a half-ruined, but still usable stronghold.
Nidas suggests that Rozrog is located by a swamp.
- Rozrog can be transliterated as 'Rosrog' in English.
