Administered by the bestial guardian Nasus, The Desert Empire’s Great Library is a place of magic and marvels. Fruitlessly many have sought it out, but this jewel of the sands travels like the shifting dunes of the desert. You see The Great Library exists in a dimension of its own with controlled entrances; the only way to enter is to be invited.

To those fortunate few they would find harmony, greeted by a community of high priests unmatched in their dedication to the guardians and their ways. These priests lived to teach the guardians word, and serve as curators of their mystical home. Under the guardians guidance the priests taught their people wisdom, ushering in a period of peace and prosperity that lasted countless years. But sadly as temporary as all things are, so was this golden age.

Renekton’s corruption heralded war throughout The Desert Empire. Mighty armies clashed, saturating the soil with ash and blood. Darkness seeped into the minds of many, poising them with delusions of gods; the priests of The Great Library were undoubtedly not immune. Many priests became arrogant believing themselves the gods chosen ones, they became among The Corrupted. Involvement in the war became the central issue, but the debates turned to arguments, arguments to fights, fights to bloodshed. The Great Library descended into chaos, disappearing from the face of The Desert Empire in its greatest time of need.

Within The Great Library the few priests that had remained humble and loyal to the guardians were fighting a losing cause. With halls thickly stained with the blood of brothers, and the victory of The Corrupted close at hand. In the darkness of The Great Library’s inner most cloisters, a priest of little significance considered an eternal burden.

By sacrificing his mortal body and transferring his soul into an ancient amulet of dark power. He could transcend into a powerful shape-shifting sand spirit, a champion of the sands capable of turning the tide of battle. But at what cost? This dark artifact had been sealed away long ago for a good reason.

Of unknown origin the amulet’s last host was plagued with a hunger for all forms of energy. At first the host drank the rays of the sun and the movement of the howling winds, but the hunger remained insatiable. When the host gave in fully to the hunger, it descended into madness becoming a mindless monster with no mercy for the guilty or the innocent. Recognising that the creature was beyond saving the bestial guardians put an end to the host hiding the amulet in the depths of The Great Library for what they though would be forever.

Euler would have to control the hunger to avoid the same fate and channeling it to feed for the benefit of his allies and the woes of his enemies. By accepting this ‘ascendance’ would mean a curse to forever battle the all-consuming hunger of the amulet. For Euler the choice was easy.

With a roar that resounded throughout The Great Library, The Golem emerged with a singular eternal purpose fueled by the lowly priest’s unparalleled devotion. To protect his people. Leading the loyal priests they cleansed the temple of the damned, the amulet strengthening the Golem with each fight. Emerging victorious the priests called themselves The Enlightened, and on returning to the war unleashed the limitless power contained within The Great Library on the heretics of their homeland.

Earth was torn asunder, fire rained from the sky, fortresses were swept away, armies washed away. Death was the lands most intimate companion. Renekton armies were all but devastated; never would they pose such a threat again.

With The Golem as their new Gate Keeper, The Great Library knew peace again… at least for a while. The coming of the portals again brought turmoil to The Desert Empire, with hostile beings emerging across the land. This new and terrible threat forced Nasus to depart on a quest to seal them, inviting all who could follow.

The malevolent forces of the portal sought power, and The Great Library shone like a star in the all-consuming darkness of the void. With the fabric of reality weakened, the powers of the void easily breached The Great Library’s dimension creating portals from the void to directly within the very halls of The Great Library. A circumstance reminiscent of dark days gone by, The Enlightened’s home was threatened again.

Armed with devastating spells, armies of summoned elementals and mystical creatures the priests fought alongside The Golem tooth and nail, hall by hall but to little avail against the endless hordes of the void. With The Great Library in greater jeopardy than ever they desperately needed Nasus, and so the Golem their most capable soldier was dispatched to locate him in the distant land of Runeterra.

Arriving at Valoran finding the famed guardian proved trivial, his power was a continent wide beacon. Though on reaching him, to the The Golem’s dismay Nasus refused to return. While his task was incomplete, the entire Desert Empire remained at risk. Instead Nasus proposed an alternative.

A pact could be made with the legendary Summoners of Valoran. In exchange for The Golem’s participation on the fields of justice, the Summoners would empower the priests of The Great Library with power enough to hold off the void for as long as necessary.

For Euler the choice was easy.

Euler disintegrates, transforming into a dune of sand that leaves a sand trail of maximum length 400/ 500 / 600 on movement. Whilst in this form he cannot perform basic attacks. Any enemies who walk on the sand trail suffer some damaged. After a 6 / 7 / 8 seconds Euler returns to Golem form.

Activating this ability again temporarily transforms Euler and his sand trail into an impassable Sand Wall for the remaining duration of the ability. During this time he cannot move or perform basic attacks.
