Rozrog stands as the legacy of actions taken by the elves.
In the non-canon story, the castle is now the property of a certain former King Herwig and 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 half-ruined, but still usable stronghold in Wiedźmin: Gra Wyobraźni.
