Kyra`

Formerly known as Nemesis, the physical embodiment of the tower's consciousness and life force.
The tower is constructed from a material called "Nera". Nera is a biomorphic substance that can be manipulated into whatever shape one desires. The nera was created and used by the Kimerra as a way to quickly and easily construct buildings. Nera is actually biological, living, although it normally does not have consciousness. The tower existed for hundreds of thousands of years before it became sentient.
Kyra's body is made from a highly advanced form of Nera as well as actual human DNA. Where the original Nera was restricted to a deep blue colour and not very capable of taking humanoid form, with the addition of human DNA, this advanced version seems to be able to recreate an actual human body in every detail.
Her body is human in absolutely every detail with the exception that she does not have normal blood. What flows through her veins is a liquid nera, the same deep blue substance that created the tower. As a result of having Nera in her veins, she retained most of not all the abilities she possessed before this change.
