Games
Not much is known about Sailor Eldritch's past, but it is known that he works at the docks in Canalave City and lives with his wife and son in town. As well he operates the boat that can take players to Iron Island and Fullmoon Island. Helping his son is a requirement for the Darkrai event in Pokemon Diamond, Pearl, and Platinum.

Eldritch's son
In the games, sometime after the player has obtained the National Dex, Eldritch's son falls into a nightmare state causing him to thrash about in his sleep. He also mutters something that hints that Darkrai is haunting his dreams.

When the player meets Sailor Eldritch at this point, he will request their assistance in healing his son. Eldritch will then take the player to Fullmoon Island where they will encounter Cresselia, who will flee and leave behind a Lunar Wing. The player returns to Sailor Eldritch and gives him the item to heal his boy. This task must be completed in order to get Darkrai.
