The owner of this treasure located in Eagle Beak Rock must have been a person of high status and immense wealth, allowing them to have collected treasures from nearly all over Europe.
Nevertheless, this creates a huge problem for Leonard and the others during their identification process, because after the removal of family marks, it is downright unclear where these items originated.
"It seems figuring out the true origin of these pieces of jewelry is going to be somewhat of a challenge." Leonard sighed after many unsuccessful attempts to find any information about the owner, then began to use the Card to investigate further.
By now, simply inspecting the jewelry would not help in identifying the owner, so he had to resort to using superhuman powers to resolve the matter.
The first Card that Leonard used was [Detection (N)]. Initially, he assumed the most valuable jewel detected would be the seal ring from the Alexandria Library, but surprisingly, it turned out to be a ruby ring.
