Otto Hightower in House of the Dragon is the scheming former Hand of the King who helped push the Greens into power, then later ended up imprisoned and, in the latest season, killed by Rhaenyra.

Quick Scoop

He was one of the main architects of the civil war: he encouraged Alicent’s rise, backed Aegon’s claim, and spent much of the story maneuvering for control at court.

What happened to him

• He was removed as Hand and replaced by Criston Cole.

• He was later held prisoner in the Red Keep’s dungeons.

• In the latest episode covered by these sources, Daemon finds him and Rhaenyra executes him, beheading him in a dramatic scene.

In the books

In Fire & Blood, Otto is also beheaded, but the sources here note that the book does not specifically say Rhaenyra is the one who does it.

Plain version

So, “what did Otto Hightower do?”: he helped ignite and steer the Targaryen succession conflict, and his story ends with imprisonment and execution.
