Secret Power

Lena has nightmares about people being attacked by shadows. She goes to investigate and meets a small boy named Spencer who she saw. She then witnesses Spencer's mom being abducted.

The boy mentions that one of his Cecil and that Cecil's dad had been kidnapped 2 weeks prior, coinciding roughly with when Lena's nightmares began.

Both of the kidnapees were Seijin.

Lena intentionally uses her powers and allows herself to be captured to find out where people are being taken. Mahad and his almost-girlfriend TRY to stop her but they are TK-stopped. Lena tells them to follow in the airplane.

Lena discovers the kidnapper is a woman named Shinseiki, who claims she alone can fulfill the Prophecy and reunite Skyland. The trouble is, she needs to make use of other Seijins' powers to do so, and the process could end up destroying entire blocks and killing thousands.

Shinseiki is okay with this, but Lena chooses to oppose her.
