Describe, Script

Unnumbered army etheric; Dost thou oppose his rule? Prefer then the nerves a-prick! Utmost, adverse, school! Dubious battle on those plains? Heaven, must ye fall? Throne afire? Wait for the rains! Field, get rid of all! All is lost? Nowhere I've seen. Unconquerable will. Only in a dream, machine! Immortals, pay bill. Vengeance study? Thus requite. Courage, doth submit? Hatred, sing in me and fight! Enemies to quit. Nine full days and nights ahead? Tartarean gloom. Tonight we dine with the dead. Red lighthouse a-tomb. Abashed, devil? But you stood! Awful, history? Good! Naga tomb, thy neighborhood. Nether regions, brood.
