THE LORD LAMBTON (updated) (Patreon)

An old knight who was cooked in his armor by dragonfire & fused with the swords in his massive armory. For 8 generations the Lambton line was cursed and the eight eldest sons all trained for WYRM-warfare only to meet horrible ends. But the final son did not go so quietly. 

His soul is locked in a melted armor of enchanted metal fused onto his charred skeleton. Serpentine dragons are specifically weak to the jagged form.
