Magical Be-In

In January of the year 1967, Penny and Allen Halliwell decided to host a "magical be-in" at the manor. They invited hundreds of their witch friends to come tap into the power of the Nexus and, as Penny put it, "ride the magic wave."

A warlock named Nigel heard of these plans, and saw an opportunity to slaughter a huge number of San Francisco's witches. He sent his evil witch girlfriend, Robin, to get herself close to Penny and blend in until Nigel came. Nigel did keep check on Robin every once and while to see if things were running smoothly, freezing everyone else in the process.

During the night of the be-in, Penny thought that evil covens will try and crash the party, and had everyone set up crystals around the manor to ward off evil. Robin used this as an excuse to slip into the attic and chant a spell to unleash evil in the manor before the crystals could take hold. Unknown to her, Allen, who had suspected she'd been acting funny, walked in on her in the middle of the chant. Robin killed him with a fireball. Penny heard the commotion and killed Robin on the spot. Out of concern for her friends' safety, she cancelled the be-in.

The Magical Be-In was and is very much like the Human Be-In that took place not long later after.
