After Arthur revives for the first time, he seeks out his friends only to find they've been cursed, and citizens have began witch hunts to eliminate all suspected of being fae, foe and otherwise, blaming them for the blight that befalls the land.
Venice (Gallahad) and his mother were subject to their wrath. His mother was considered a warlock despite only ever using her powers for good. While Venice had minor premonitions, his power was nothing compared to hers. His only sin was being her son.
Venice was forced to watch his mother burn at the stake, before being dragged off and crucified as a warning to other fae folk... He was left there and lived for several days. By the time Arthur found him, it was too late. He hoisted Venice off the crucifix and held his fading friend in his arms as he drew his final breath.
Upon Venice's death, Arthur wept, tears of gold bubbled over as he shook his friend's lifeless corpse, when his tears fell onto Venice, that is when he discovered he could resurrect others and not just himself...
Not long after his revival, Venice changed his name to Gallahad in an attempt to escape the wrath and unwarranted hate his name brought with him.
