Bellissa caught up with the Thief, but instead of apprehending him, she conceived a child with him, presenting him with a son, before releasing him to go and continue his intended work, which was the founding of a New Order. Thus was Oberon born, and Amber founded.
Realising that she could not meaningfully return to her father, she placed herself in suspened animation, and had herself held in stasis, with her organs removed and ritually entombed, against the day when her actions might be forgotten and she could be revived without fear of punishment.
This tomb was on the island of Minos, on St. James. This is the first mention of the realm of St. James in recorded history.
