King Amaru's Aquaduct is a region of the Cortica River in Endless Ocean: Blue World. This passageway that connects Cortica River Upstream's Spirit Falls to the Twilight Temple cavern. It is originally blocked by an ancient stone gate, and the player must solve the puzzle of the two frogs, using the Multisensor, to proceed.

Along the floor runs a narrow, long, and somewhat shallow channel, ending in the Sacrificial Well, in which the Ara Coin can be found. It is unknown what purpose this ditch served, as the surrounding geography does not support this channel being used to transport water, like an aqueduct usually is. Because it ends in the Sacrificial Well, however, we can assume that perhaps this ditch, and maybe the Aqueduct itself, were used in ancient, perhaps malevolent, rituals.

The Lacerta Coin can be found in the Aqueduct.

In-Game Description

"Only those who have solved the riddle of the sacred frogs may use this path to the temple.

The walls are covered with exquisite carvings."

Local Fauna

The aqueduct mainly contains black arowanas, and under zoom-mode patches there are guppies and altum angelfish. For a brief part of the storyline there is also a caiman here, albeit an exceptionally angry one.

Imagery and South American Inspirations

Along the aqueduct you will see identical statues of a figure holding what appears to be a dish. This may be a generic creation and not specifically based upon any South American relic.

On the walls you will repeatedly find three stone carvings containing imagery adapted from South American civilizations. Below you will find the images from the aqueduct paired with their real-life inspirations.

Inspiration 1: Quetzalpapalotl residence wall

One wall design you'll find in and near the aqueduct is an adapation of a pillar carving found at the site of Teotihuacan in Mexico.

Quetzalpapalotl carving comparison

The city at Teotihuacan was one of the largest in the early Americas, and evidence shows it was multi-cultural in nature (i.e. it cannot be labeled a "Mayan" city or an "Aztec" city). One part of the Teotihuacan site is the Palace of Quetzalpapalotl, a building named by the site's first archaeologists for the "bird-butterfly" designs prevalent there. This pillar art is an example of that bird-butterfly motif.

Inspiration 2: King Pakal's Sarcophagus

Another wall design shows a portion of the sarcophagus (coffin) lid of an ancient Mayan king. King K'inich Janaab' Pakal

Tough to see, but the carving is part of King Pakal's sarcophagus

ruled the Mayan city of Palanque for 70 years—most of the 600s—and during his reign art and architecture flourished. His sarcophagus lid is considered one of the finest pieces of Mayan classical art. it depicts a partly-reclined Pakal descending to the underworld amidst various other icons. Some insist it shows him as an astronaut, but archeologists give this very little merit.

Inspiration 3: stylized Mayan Calendar center

Many modern replications of the circular Mayan calendar feature a kneeling figure in the center known as the cargador del tiempo—the "carrier of time."

This is said to be a Mayan deity of time who is carrying the days upon its back.

No authentic Mayan Calendar artifacts seem to feature this character, however. But many artists' interpretations as well as souvenir calendars have made this image popular and enduring.
