what happened to house velaryon in got

House Velaryon does not disappear in the world of Game of Thrones ; in the lore, they remain an important Valyrian house tied closely to the Targaryens, though their power declines over time. In House of the Dragon , they’re much more prominent, especially through Corlys “the Sea Snake” Velaryon and his family.

What happened to them

• They rose as a major seafaring noble house with wealth, ships, and strong blood ties to House Targaryen.

• Their peak influence comes during the Targaryen civil war, where they are deeply involved in the conflict.

• After that era, the house loses much of its former power and political weight, which is why they are barely visible by the time of Game of Thrones.

Why they seem to vanish

The simplest answer is that the show Game of Thrones focuses on a later period, long after House Velaryon’s height. By then, other houses dominate the story, and Velaryon’s role has faded into the background.

In the current TV story

Recent coverage of House of the Dragon shows Corlys Velaryon still central to the plot, and the house’s fate is tied to major battles and succession struggles in that prequel timeline.

TL;DR

House Velaryon didn’t get destroyed outright so much as gradually decline after its peak, becoming a much less visible power by the time of Game of Thrones.
