A preserved thumb of a once-famous Rogue Trader in a canister of embalming fluid
A severed thumb in a plasteel canister. It is very important because it contains Obadiah Trask’s DNA, with which you can access anything genelocked to Trask’s family.
Obadiah Trask was last scene ferrying an Inquisitor to a heretical world in the Calixis Sector, nearly a decade ago. It is currently unknown if he is alive or dead, or how his thumb ended up in Port Wander.
