Hadrian was able to get everything out of Matai Shang and now had the knowledge the Therns hoarded over the centuries.
Dejah used some of them to help Hypos and Tharks with their food shortage issues and even created an Atmosphere modifier for Hypos.
Also, Dejah wanted to see Earth and Nuala also wanted to join in. So they decided to go and let's just say things have changed a lot and they traveled around the world, Dejah loved the different food and culture.
While they came across different groups, who had connections to Hyperborean's and one of them was from India and this was a group of Sages were able to have a chance encounter with the last remnants of Hyperboreans. They used the teaching of remnant Hyperboreans to create various artifacts.Which they called Astra, these Sages instead of the technology aspect focused on the spiritual and magical aspects.They called themselves Brahmānsh.
They modeled these Astra's after all the different things in nature like elements and animals.The Brahmānsh exist alongside normal people and help the the world with help of these Astra's.
The leader of the group always took the title Guru or Teacher.It took some time for them to trust Hadrian, but it was worth it and Hadrian became an honorary member of Brahmānsh.
While the other interesting person Hadrian met was Alexander Corvinus a Hungarian nobleman and warlord who had ascended to power in the early seasons of the 5th century, just in time to watch his home village be ravaged by a plague. Alexander was the only survivor: the bearer of a rare genetic mutation, his body was able to adapt to the virus in an immune response, causing him to become the first of the Immortals.
Hadrian found the mutation to be from elves,it was highly possible that Alexander's ancestor was half elvish and this plague mutated his already present gene.
Although this granted Alexander eternal life. However,he can still be killed if he is damaged beyond his accelerated healing power to regenerate.
But Alexander always thought Hadrian and his wives became immortal through something similar, he wasn't aware of the magical world.
Alexander called Hadrian and his wives to his wedding it was a fabulous event, but Hadrian could tell Alexander was worried about something, then it clicked he was worried about his wife's mortality.
Hadrian passing a drink said, "You don't have to worry about her mortality, I have a way to make her similar to you?"
Alexander was surprised and asked"You can do that?
Hadrian nodded and with a wave of his hand he conjured a tiny model of a dragon,it was a miniature Hungarian horntail, that rears up angrily, lets but a roar, and a tiny ball of fire.
Alexander watched the small dragon with awe,while Hadrian told him basic history about the magical world and added"To make your wife the same as you,I will need some of your blood."
Alexander nodded and gave his blood, Hadrian and Dejah studied it found the gene to be amazing,the Corvinus Strain as Dejah called it, a recessive genetic anomaly that, when inherited in its active form, gives its carrier immortality and superhuman strength, while additionally possessing the capability for another stage of mutation when subjected to gene-fusion. This recessive strain is activated once it mutates with the genes of one or more other species. The example of the Corvinus Strain is capable of combining properties from any race that would otherwise destroy themselves on contact due to the incompatible components contained at their cellular level.
Hadrian's own gene was similar and he was using this to help his wives.
