King of Spikes

One thing seems to be arbitrary for the Kings of Spikes; their sadism.

They were all notorious for executing, not just the perpetrator, but also his kin in the same manner.

Execution Method
The accused and his family were tied to wooden posts, facing each other. Then the killing would commence, starting with the youngest of them. The King would drive a wooden stake through their throats one by one, until the only one still alive was the accused.
