Ransisc was a steerer on the Roxolan star warship Indomitable. He had one apprentice, Olgren. It was Ransisc who first observed Earth in 2039. He tolerated Captain of Foot Togram's presence at his observation post since the Captain was experienced and had a good eye for detail when observing at a telescope eyepiece. Togram also had a decent hand with quill and paper so Ransisc let him spell himself and Olgren at map sketching.
Ransisc was captured by humans during the invasion of Earth and reunited with Captain Togram, a fellow prisoner, afterwards.
