A potent kit indeed
More choices ahead
A vital dam plunge
Fly behind the mountain
A dome from the past
A forgotten dig site
A telling dead end
A crystal crevasse
A crystal den
Fly over the dig
Fly through the wreckage
Power User
A high mountain vault
A brave basin drop
All the choir is here
Remember my song
Commited to a wave
Modulation memory
