This one is NYTW-based, where Orpheus knows the truth behind Hadestown and Eurydice is more naive to it.
Afterlife
Orpheus didn't know much about Hadestown, but from what Hermes had described, and the rumor mill had spread, he knew it was to be avoided at all costs. Mr. Hades was a cold, cruel man on his worst days and an uncaring boss on his best, cajoling people into signing their lives away for nickels and dimes.
As someone who lived and thrived in the open air, singing to all who approached, Orpheus didn't understand the appeal. Why trade blue skies for a ceiling 6 feet under; why trade your breath for an afterlife of glazed eyes and hunched backs, working your death away?
Orpheus didn't understand, but when the Fates sang of riches in every pocket and wine on every pair of lips, of wealth beyond measure, Eurydice was sure she understood.
Hadestown was a land of opportunity in troubled times, and the afterlife would let her rest in peace, free from the volatile world.
It was only when the deal was signed that Eurydice realized she was mistaken.
