Made liberating angels space combat themed chapter. Starting sector was full of orks, tau and heretics. In seemingly vain attempts to slow down ork waagh the dark age of technology battleship was discovered. By emperors blessing the new ship appeared on that planet each month, soon the chapter had several liberation fleets with 7 slaughtersongs in each. This made lifes of heretics and xenos short and miserable.
After liberating STC from mechanicus vaults , the red robed guys got insane for some strange heretical reason, which I cant understand, and they refused to provide the chapter new weapons. So the liberty angels had to perform liberation campaign on the forgeworlds. If the final destination of your path is sainthood, you can afford yourself some minor war crimes anyway.
After nuking forge worlds, the exact copies of marines began to appear, increasing chapter numbers. One more emperors blessing!
After inquisition not understanding doctrine of achieving great sainthood through crimes like using demonic weapons, breaking codex size by accumulating five thousands of marines ,vanishment of inquisitors trying to inspect the vault full of demonic artifacts or exterminatusing shrine world for not praying enough and to make ecclesiarchy notice epic sainthood of the chapter, the imperial navy , sisters of battle and inquisition for some strange heretical reasons became as heretical as mechanicus, so they were soon gifted liberation.
Corrupt and vile eldar farseer tried to warn the chapter master, that there may be some heresy in saint deeds of his chapter. Of course such false accusations could not end up without liberation. Then the final liberation of eldar craftworld with exterminatus device ended up with save corrupting crash. May the bell of the lost souls ring 5349 times.
The infinite slaughtersongs and replicating marines bugs were prety funny.
