The Tomb of Eilram was a burial site situated on the world of Zeffo. The ancient Zeffonian race constructed it as the final resting place for the Zeffo Sage named Eilram.

Originally, the Zeffonians built the Tomb of Eilram as a training facility. Post-construction, the Zeffonians responsible for its creation left behind a collection of wind chimes. It was hypothesized that these wind chimes were intended to summon the sages for prayer whenever the wind passed through them. This structure served as a proving ground for Force-attuned Zeffo Sages. Ancient rituals involving Zeffonian meditation relics were conducted here to train Force-sensitives and aid them in their quest for knowledge. Eventually, the site was transformed into a tomb to honor several Sages, notably Eilram, a Sage deeply revered in Zeffonian society. Eilram was interred in a chamber adorned with an elaborate carving of a wroshyr tree, commemorating their pioneering relationship with the inhabitants of Kashyyyk and their appreciation for the planet's verdant landscapes. The tomb was protected by several Zeffonian Tomb Guardians. At some later point, an individual or group destroyed a Zeffonian Tomb Guardian alongside an ancient artifact crafted as an offering to the wind. Sometime before the downfall of the Jedi Order in 19 BBY, Jedi Master Eno Cordova and his explorer droid, BD-1, explored the Tomb of Eilram. During the exploration, Cordova documented the various glyphs, artworks, and artifacts discovered throughout the tomb.

In 14 BBY, during Cal Kestis, a fugitive Jedi Padawan's initial mission to Zeffo, Kestis journeyed to the tomb with the intention of re-establishing the Jedi Order. Upon arriving at the tomb's entrance, Kestis employed the Force to decelerate a storm, allowing him to access an elevator within. Inside, he descended to the tomb's subterranean levels, reaching a puzzle chamber. Successfully navigating the puzzle using wind vents, Kestis encountered another challenge. He overcame it by utilizing a nearby wind vent to propel an energy sphere, enabling it to swing like a pendulum and allowing Kestis to traverse a chasm. Eventually, he arrived at the main puzzle room and engaged in combat with an ancient Zeffonian Tomb Guardian. After defeating the Tomb Guardian, he utilized the surrounding wind vents and his Force abilities to reach a large door. There, he experienced a Force vision from his past, which aided him in rediscovering how to manipulate objects with the Force. With this regained ability, Kestis entered the chamber where Eilram was entombed. BD-1 then presented Kestis with a recording of Cordova within the tomb. In the recording, Cordova highlighted the wroshyr carving, indicating the Zeffonians' historical ties to the jungle planet Kashyyyk. He concluded by suggesting that if the Zeffonians had been on Kashyyyk, Wookiee Chieftain Tarfful would be aware of it. This prompted Kestis and his team to travel there.
During his exploration of the tomb, Kestis employed a Force power known as psychometry to glean insights into past events within the tomb. While investigating, Kestis opened a chest in the main puzzle room containing a Balmgrass BD-1 skin. Another chest, located near Eilram's burial chamber, was opened by Kestis and contained Slivian iron, a material suitable for constructing a lightsaber. A third chest, situated near the main puzzle room, was opened by Kestis and contained the material for the Outlander poncho.

The Tomb of Eilram was designed for the video game Star Wars Jedi: Fallen Order, which was developed by Respawn Entertainment and released by Electronic Arts on November 15, 2019. The location's initial reveal occurred in Cal's Mission Trailer on September 26, 2019. Artist Bruno Werneck contributed concept art for the tomb. Mirroring the broader game design, the location was significantly influenced by 3D Metroidvania-style design - an action-adventure game subgenre characterized by expansive, interconnected maps with pathways that unlock as players progress. Initially, the tomb was conceived as a series of wind-based puzzles. This concept later evolved to encompass various narrative themes. For instance, the Fallen Order team sculpted a canopy into the tomb's windswept formations to showcase the Zeffonian's reverence for Kashyyyk's Origin Tree. This emulation of natural elements informed the organic patterns prevalent in ancient Zeffonian architecture.

The game's development team also incorporated a hidden chamber within the tomb, containing low-polygon models of Boglings, Zaur, and Yoda. Accessing this room and viewing the figurines requires players to first descend using the elevator at the tomb's entrance. Upon exiting the elevator, the player must exit the elevator by using the crack in the elevator where the player will enter a room full of wind vents and moveable Zeffonian energy spheres. On the player's left where the Tomb Guardian is, there should be a slot for a Zeffonian energy sphere. Placing an energy sphere into the designated slot unlocks the location of the easter egg. Players can reach the secret room and observe the easter egg by returning to the main elevator, proceeding to the circular platform with the ball at its center, and leaping to the grate from there. Successfully reaching the gate allows players to climb up and access the secret room containing the easter egg.
On May 4, 2020, Respawn Entertainment launched a complimentary content update for the game across all platforms. This update featured a combat challenges mode, enabling players to engage various enemies in pre-set waves from specific locations within the game, including the Tomb of Eilram. The update also introduced a battle grid mode, allowing players to confront any number of enemies at diverse locations in the game, including the Tomb of Eilram. These modes are accessible via the meditation training system within the game.
