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