The monks took in the PC's after the defeat of the raiders & told the PC's about their guarding one of the Eternity Crystals. They also found the crypt of Sir Briane aka the Silver Knight whose descendant was the champion of the monastery until he was murdered in battle defending his brothers. The psion crystal matrix was destroyed during the raid and the knights are awaiting appearance of a new champion (more on him coming up).
The PC's found thousands of protective spells in the Alko language carved into the foundations of the monastery. These descended deep into the crypts & around the parameter of the foundations of chapel of the monastery which originally was a converted Roman temple.
Can the Templars hold out as the sky fills with the flying saucers of the Aldebarans raiders with the PC's as they await the arrival of the Templar Knight's new champion? Can they resist the temptation to ignore the raiders that are ravaging the countryside? The Aldebarans raiders came straight outta of Light City Foes: Stardust From Halls of the Nephilim.
And what secrets does Tegel Manor hold in the wake of the legacy of the Eternity Crystals? Tonight one of the PC's saw the burning psionic eyes of some renegade psion who works with the Aldebarans raiders! Even as this is going on the ghosts of the Templar knights don't rest easy in their crypts! Something evil beyond all experience stirs out in the battle fields & hungers for the souls of the adventurers. Something from TSR the Fiend Folio is coming for the party next week!
