Block Yard is the first property that players can claim in LEGO Universe. In order to claim it, players must defeat the Spider Queen. When the Spider Queen escaped from the Paradox Research Facility, she fled into the Maelstrom Mine. There, she discovered a launchpad to Block Yard, and used a Paradox Darkwarp Rocket to fly to the unclaimed property. She then created a dense cloud of Maelstrom energy, which floated over Block Yard and the Launch Area.
