Steloc Aethon
Captain of the 19th Company, The White Spider
Also known as The White Spider
Homeworld: Calth
Steloc Aethon, the White Spider, was captain of the Ultramarines 19th and a Calth native who fought the Underground War in the arcologies of his own home. He was not Aethon Shaan of the Raven Guard. The name is where the resemblance stops, and the caves did the rest.
He held tunnels against the XVII Legion until Kurtha Sedd ended him, a company captain slain in the dark by a Word Bearer who had come to Calth to unmake it. The White Spider died on the world that had raised him, which is a special kind of theoretical.
The 19th lost a native son in a war that specialised in those. Ultramar still has the title in the Calth lists. The caves keep the body. Do not file him under Deliverance. That is a different Aethon, and a different Legion's problem.
