About that containment device that was restraining Ariels in Strive and the one in Elphelt's SIGN intro, is the device actually Cyprus technology itself since it is strong enough to restrain Valentines? I am not sure if the story ever explained what it is and what it actually does.
Cyprus tech has more to do with firearm weaponry than any sort of seal or restraint, and it was the Conclave who funded most Cyprus tech (Ariels was a hidden backer as well, according to King Daryl).
That said, Ky stated that they performed all manner ofĀ ātestsā to determine if Elphelt was human or not... and they did confirm she was a Valentine.
Ky, Leo, and Daryl agreed to put her in the restraint as a temporary measure until they could do something about Elpheltās sister Ramlethal, since it was Elphelt who first gave them the intel, but she did not know to what extent the Conclave or Ariels were involved at the time.
The condition was that Elphelt would be restrained until it came time to incapacitate Ramlethal, because of the unique power both sisters have over one another.
At first, Ky asked for Leoās approval, but because Leo wasnāt immediately receptive to the situation, Ky went over Leoās mandate of keeping Elphelt restrained, which caused a bit of friction, but was a risk Ky was willing to take.
Thatās all we actually know about the restraint device, so most likely it was something all three Kings came up with (though, itās still very possible it is based on Cyprus technology, though we canāt say for sure.)
Itās still a mystery how Elphelt managed to get her Cyprus guns in the first place, though itās possible Ariels had a hand in that.
