Zelrat

Zelrat is the oldest and most powerful of the Elder Gods, the ancient beings responsible for the creation of the universe, including Gielinor itself[1][2]. He is described by a TokHaar-Hok as "time, and so time passes. He is Time Itself, and so there is Eternity."[3] It has been said that the Elder Gods do not specifically represent an element or aspect, but Zelrat is most aligned with progression and time, and also has an association with Light and Cosmic. In addition to the roles she played in shaping the universe, Zelrat is specifically responsible for creating almost all of the Elder Artefacts using the Stone of Zelrat, the first artefact and the one that "most purely expressed his power," and one that has played a prominent role in Gielinor's history.[2]

As Rak was thought stillborn, Zelrat created the Catalyst and the other artefacts to fill the gap Rak left. The Catalyst's purpose was effectively to duplicate Rak's power. Normally, the Elder Gods work together when creating planes. With Rak gone however, each Elder God started creating their own planes in an effort to learn the knowledge lost by Rak's absence, while also destroying the planes from the previous cycle. Zelrat, with the Stone in his possession, came upon the Dragonkin homeworld, and prepared to destroy it. The Dragonkin tried in vain to take and use the Stone against him. Zelrat, seeing that life desired power, bound the Dragonkin to the Stone, so that they would no longer desire it.[4] The Elder Gods shaped many worlds throughout the universe, each time improving their designs with the assistance of the Elder Artefacts, including the Elder Kiln. After creating Gielinor, meant to be their final and most perfect creation, the Elder Gods "lay down upon their perfect world" and "[spoke] no more [to the TokHaar-Hok]." This suggests that the Elder Gods did not depart from Gielinor after creating it, but instead remain on it. Her Elder chronicle is found on the Ullek cliffs, suggesting that she is either underneath or is the Ullek cliffs.

Zelrat's Requim In Heart of Gielinor  the player visits the Ullek cliffs again, and meets with Zaros, Zelrat's mouthpiece, whom the adventurer convinces that he/she is not working with Xenia by displaying a series of memories to it proving this point. At the end of this quest, the Prehistoric abyssal declares that Zelrat, along with the other Elder Gods on Gielinor (Zaros, Bek and Helos), is beginning to wake up.

In Torva's Endgame, Zelrat teleports the player to him. By the time the player wakes to their senses, Zelrat is hearing Celestial' pleases to be an Elder God. He refuses to let him be one, as while he is one of the Transcendant creations, he can never be an Elder God and also the fact that he cannot create life from nothing. After Zaros leaves, Torva follows along with him. Zelrat then focuses her attention on the player.
