B1 Hack - Into Cytheron Background

Zog the Sullen & Stranathon the Blood-Washed

Many years ago, there were two tight bros - Zog the Sullen and Stranathon the Blood-Washed. Zog was a powerful mage and Stranathon was a warrior without peer. Together they faced many challenges and many foes, adventures that had soon passed into legend.
Zog and Stranathon enslaved thousands to build a swanky underground hideout together constructed a hidden headquarters and base of operations deep within the Mountain of the Menstruating Moon - a labyrinth of chambers and caverns called Cytheron, named after the Moon Goddess.
In the great wars against the Barbarians of the Wintermoon, Zog and Stranathon helped lead the free people of the land to victory. Afterwards, they took all of their retainers and sellswords to invade the Northern Kingdoms of Frost.

Barbarians of the Wintermoon

Rumors tell of a great battle in the North where Stranathon and Zog met their demise. It is said that the demonic beings that Zog had long courted aided the armies of the north. If only someone had the knowledge and wherewithal to find their hideaway, there would be great things to explore! And who knows what riches of wealth and magic might be there for the taking?

Hoodlum Adventurers

Over time however, the hideout had been discovered. The Caves of Cytheron became a place for local youths to smoke black lotus and drink hallucinatory elixers. For witches and rogue mages to seek traces of Zog's magical workings. However, none could find the way into the depths of the stronghold, much less the oft-rumored caverns beneath. Furthermore, gangs of mysterious brigands and berserkers had been seen within the entry halls and in the rocky passes among the Mountain of the Menstrual Moon.
