In the booksEdit
In the A Song of Ice and Fire novels, Baelor Blacktyde's father was killed in a battle of the Greyjoy Rebellion. Baelor was taken as a hostage for eight years in the city of Oldtown. Upon his return to Blacktyde, Baelor had converted to the mainland's Faith of the Seven. Nevertheless, several Blacktydes gather around Balon Greyjoy when he crowns himself King of the Iron Islands again.
Lord Baelor Blacktyde supports Yara Greyjoy (called Asha in the books) after the death of her father. Asha's main support base is Harlaw island, the wealthiest of the isles, ruled by her maternal uncle Rodrik. While Harlaw and Blacktyde support Asha, Euron gains control over Pyke itself and Orkmont. The other three islands - Great Wyk, Old Wyk, and Saltcliffe - waver between who to support. Fearing a civil war, Aeron Damphair calls the Kingsmoot to try to resolve the succession.
Lord Blacktyde vocally supports Asha's pro-diplomacy position at the Kingsmoot: he lost his father in the first Greyjoy Rebellion and is thus more wary than others that they are only going to keep losing more fathers and sons in a war they cannot hope to win.
After Euron Greyjoy surprisingly wins the Kingsmoot, Asha immediately flees before her uncle can detain or harm her. Many of the other lords such as Rodrik Harlaw fall into line, but Lord Baelor defiantly refuses to acknowledge Euron as his king. In response, Euron has Lord Blacktyde publicly executed, his body carved into seven pieces in sarcastic reference to the Faith of the Seven which he had converted to.
