Long ago, after the conspiracy that Queen Helen and Prince Aiden was exposed, Rion sentenced Queen Helen to burn for the use of black magic. Meanwhile, Aiden, who at that time was not proven to use black magic just like his mother, received 'the boat' punishment.
That was after being whipped, which caused his skin and flesh to be torn apart, Rion chose 'the boat' punishment to end Aiden's life.
Aiden's body was smeared with honey and milk. He was then placed on a tree trunk that had been perforated with the head and legs protruding. After that, Aiden was forced to drink honey and milk, which caused diarrhea before being sent away into the sea.
The boat convicts will usually die after days of dehydration, or from the bites of insects that gathered due to the sweet smell of honey, mixed with the stench of the convict's vomit and feces.
It was a form of Rion's cruelty, as well as an outlet for his anger because Helen and Aiden had made him sentence Rose and Lucas to death.
