From the Comic-Con Toucan Blog:

The Holy Grail is the most sought-after treasure in history, requiring the constant protection of the legendary Knights Templar. At Knightfall: Guardians of the Gear, Comic-Con badge-holders are invited to store their personal treasures under the same protection: the watchful eyes of the templar knights. Stop by to store your swag and steal a glimpse of the elusive Holy Grail.

Guardians of the Gear will be located behind the Omni Hotel (near Petco Park), and available at the following hours:

• Thursday – Saturday: 11:00am – 7:00pm
• Sunday: 11:00am – 5:00pm
