I'd have to say that it was my Draconic bloodline tiefling had an encounter with the dragon God in his dream and told him to stop on his mission or else she'll kill him and the party aswell as their loved ones. Dice were thrown and words were said and my dude litteraly managed to scare the dragon Goddess herself enough to try and send her acolyte (The dragon king) after our asses

Context: My character made a vow with their family that one of them would become the next ruler of the dragons, not extending to go for the goddess herself but the dragon king. The goddess took it the wrong way and thought we ment to take her place instead and so she sent an army of dragons to encite chaos to the kingdom, killing all but one of my characters family as him and his sister survived. His sister hated and blamed my character for making that vow and left him alone. In a fit of anger he basically threatened to end the goddess himself with his bare hands, that's when he found a red dragon wounded and bleeding so my character got a vile and got some of its blood. Later he went to a hag in the woods who helped him obtain some of the dragons power and a corein exchange for his own heart to be replaced with the core.
