Prologue of Rareonce-Revelation of the Weavers

You run over and slice down half the imps attacking your captain. You fight back to back, slashing down imps. Theres only 100 humans left and imps are still pouring out. You fight back until theres only ten of you left.

Then suddenly, angels come from the heavens and strike down plenty of imps, humanoids with white wings, fly down with white swords, slashing and helping the angels and you, beating off the rest of the imps.
