Beta Team follows tunnels leading out from Ched Nasad . Beta Team is ambushed and captured by drow, then interred into a work camp. They are broken out by Nathxena Fey and meet for the first time. Together they infiltrate House Helvirae and uncover that they are working with the archdevil Fierna.
Beta Team enters the Shadowfell and fights their way through enemies. Making their way through dungeons and fighting House Helvirae troops, they recover a piece of solid shadow - a magical artifact for the portal.
Beta Team is alerted that Nathxena Fey had been captured in Menzoberranzan by House Helvirae. They rush there to find her being used in a ritual to create the spell. A large fight ensues where the team are pushed to their limits. They are too late however, and Nathxena Fey is killed in a ritual sacrifice. An explosion of planar causes them all to be transported to Sigil.
Beta Team is informed they need four elemental energy devices to construct an anti-portal device. They travel to the elemental planes of water, fire, air, and earth to charge the devices at elemental vortecies. These vortecies are places of interaction between the planes, creating large amounts of planar energy. After charging all the devices, they return to meet up with Nathxena Fey at Ardent Keep.
