Pontius Mengsk destroys House Cygnus

Political event

After House Cygnus rebelled against House Mengsk and stated their resolve to secede from the Inquisition, Grand Inquisitor Pontius Mengsk utterly annihilated the noble house and its leadership, causing its members to flee and assimilate into the remaining houses. Pontius left only the lake they presided over as a reminder to the other noble houses that the cost of betrayal is high.
