Season 6: Episode 5: A church beyond heaven

While on our travels, the Elysium encounters a strange hail which quickly becomes apparent is automated and on a loop

A vast city ship, low warp capable and looking more citadel/chapel than ship, overtly ornate, spires and iconography litter the hull.

the automated message reveals the ship to be on a holy mission, sent from its world to spread the message of their gods to all whom might listen, it even welcomes us to come aboard but upon further hails there is no reply.
