History
The giant goldfish Ambrose, loyal pet of Lady Dorma, attempted to retrieve the Unforgotten Stone and was mutated by its power but not corrupted, lacking an inner darkness for it to exploit. As the Black Tide were poised to slaughter the city of Atlantis, Ambrose returned with the Unforgotten Stone. Dorma channelled the Unforgotten Stone's power and used it to seal the Black Tide in mystical ice, but was briefly mutated into a monster before Ambrose consumed the eldritch darkness from her, Namor, and Attuma. Following this, the Unforgotten Stone was once again sealed away.[2]
