When our guild (Lords of the Dead) was planning to do an event night and open Temple of Balthazar, I tried researching the meta-event chain and had trouble finding concise information. This prompted me to put together a tutorial guide, viewable at the following link: Assault on Balthazar
I hope you enjoy!
And if anyone on Blackgate is interested in participating in future LotD guild activities, check us out at Lords of the Dead
