Tuseok
Ancient Tuseok, also known as the Dragon of Serapis[2] (possibly alternatively spelled Dragon of Sarapis, see note below[1]), was a Contemptor Dreadnought in the Salamanders Legion who was attached to Cadre Obsidiax.[2]
Tuseok was already a highly decorated veteran of many of his Legion's battles before it was united with its Primarch Vulkan. He rose to the rank of Captain before being mortally wounded in the Battle of Khur and being interred in a Dreadnought frame. He is also known to have participated in the Segmentum Solar pacification campaign with the Saturnyne Armada (as denoted by the Saturnyne Ram insignia on his armour). He had also been decorated by Vulkan for his heroic actions during the conquest of Serapis (white Firedrake skull with lightning bolts insignia).[2]
Ancient Tuseok was eventually killed in the Dropsite Massacre on Isstvan V, but his self-sacrificial actions repelling waves of Night Lords gunships contributed to the escape of a small contingent of Cadre Obsidiax and Raven Guard.[2]
Note
Quite possibly Ancient Tuseok is the Salamanders Dreadnought referred to in the final battle of Eduhkar. There the Salamanders Dreadnought bears the inscription Dragon of Sarapis while Ancient Tuseok bore the name Dragon of Serapis.
