In the books (Fire & Blood), Larys 'Clubfoot' Strong meets his end during the 'Hour of the Wolf.' After Aegon II dies, Cregan Stark marches on King's Landing to clean up the corruption. Larys is arrested for his role in poisoning Aegon II. Given the choice between taking the black at the Wall or execution, Larys chooses death..asking only that Cregan chop off his clubfoot so he doesn't have to limp in the afterlife. Cregan gladly decapitates him with his Valyrian steel sword, Ice, completely ending House Strong's main line.
