Hmm, for now only one name comes to mind, I will probably edit and add more later:
Gamble.
Aaand here's a couple more ideas:
Tonic
Muddle (oops Kabuto already suggested that name
)
Spark
Mystery (somehow that word doesn't look right...) /Mysterious / Myst
Flare
Flair
Come down from the mountain, you have been gone too long
The world is alive now, in and outside our home
You run through the forest, settle before the sun
Darling, I can barely remember you beside me
You should come back home, back on your own now
