HMS Invincible was a heavy cruiser of the Royal Manticoran Navy.
It was one of the ships deployed to the Silesian Confederacy on anti-piracy operations. Simon Chakrabarti served as Executive Officer around 1883 PD, his last active-duty assignment. (HH10)
The Invincible was likely decommissioned or renamed prior to 1904 PD, as a battlecruiser of the name was in service at that time. (HH3)
