After dystopian Eftos [Opp. 01-42] Eftos tracked a sci-fi legacy.

1) Exo [Opp. 43,50] a noisy filigree into nature, for headphones.
2) Trivy [Opp. 44,47] one thousand synthesizers, a facile flow.
3) Syntari [Opp. 45-46] alien arrangements, deep space adagio.
4) Vex [Opp. 48-49] a forlorn world, abstraction and isolation.
