Daz was a Nomai scientist who was the spouse of Cassava and the brother of Avens. He was involved in building the Memory Storage Prototype which became the Nomai Masks and he was the Nomai the Statue bonded to in the Statue Workshop; he worked with Phlox there. He conjectured with Phlox and Cassava about if the memories were sent back in time if it would be like time travel for the being. Daz says the effect would be similar.
Daz suggest to set the power level for the Orbital Probe Cannon lower because Mallow and Avens will just raise it because they are just so "enthusiastic".
Daz's remains are presumably near Cassava's on the Construction Yard, going there after the postponing of the Ash Twin Project.
