This Is What You Are

 is the 1st track in the Warframe Soundtrack. It is a choir song which plays in The Second Dream, during the revelation of the Tenno's true form. It is also partially played in The War Within, during the Tenno's first independent Transference to their Warframe.

Trivia

 * At the beginning of the song, the solo hymn followed with a collective choir is meant to symbolize a mother (Margulis) singing to her children (Zariman children), the children singing back in return. This was apparently confirmed by the composer, Keith Power.
