Whale's Weeper is an Unexplored Territory in Xenoblade Chronicles X. It is located inside Whale's Gullet in Noctilum. The entrance can be accessed by turning left after entering Whale's Gullet, past a ledge that can only be accessed with some difficulty by the jump of a Skell. Whale's Weeper can also be accessed without having to pass through the Whale's Gullet by jumping a ledge in Redsnake Pass. As with all Unexplored Territories, its discovery yields an achievement ("Welcome to Whale's Weeper").
