Theaboros Archon

Based on the following description:
Theaboros has changed, and not for the better. It still
has wings but it floats instead of flying, lingering impossibly in the air between
each step. Its railgun is gone, and its head now projects upward and backward
in the shape of a huge ring that glows crimson with exhaust heat and vented
antimatter. Amynta immediately sees it for what it is: a radar disk and the
source of the jamming that currently has the rebel force scattered and
disoriented. But she’s more struck by what it reminds her of. It’s like those
creatures Amynta remembers reading about in old myths.
An angel. That’s it. Amynta is staring at a fallen angel.
Theaboros moves slowly, following behind the advancing Imperial
formation in a manner Amynta can’t help but think of as arrogant—defying
gravity, taunting the rebels with its apparent fragility.
