The children of the Maker.
There are two types we have encountered so far: green markings and blue markings. Both humanoid1..
The one with blue markings that I had time to talk to had lines up to just under the eyes with (4?) dots on one side, above the eye the dots (3?) were on the other side of the lines.
The types are connected by what was described as a shared subconscious; but more than that, when the dragon’s bone2. of one shattered it shattered the dragon’s bone of all the others of that type. This did not kill them. Their bodies are made out of a material much like our flesh, but more perfect - it does not decay.
The one, a blue type, who followed us back from Sufrant has given himself the name Cobalt.
There are apparently other sorts, such as the “Monsters” created for the arenas of Namassis. But the Nephilim we met had not seen any in some time. He said they were all kept in a different part of the citadel, but also that they weren’t built to last in quite the same way as his kind were.
Each had dragon’s bone at its core, as we have hearts.
