Vulcan fell down for a day and a night, landing in the sea. Unfortunately, one of his legs broke as he hit the water, and never developed properly. From the surface, Vulcan sunk like a pebble to the cool blue depths where the sea-nymph, Thetis, found him and took him to her underwater grotto, and raised him as her own son.

Vulcan had a happy childhood with dolphins as his playmates and pearls as his toys. Late in his childhood, he found the remains of a fisherman's fire on the b
