Gilberta, also known as Galadriel, is the queen of the dark elves of Zeruel. Depending on the route the player took to reach the boss room, Gilberta will either be at full life or half life, and survive the poison for 200 seconds and 100 seconds respectively, after which players will lose the protection of her water shield.
Gilberta is first encountered in Zeruel, where she confronts Dahlia and reveals the traitorous dark elf's true intentions to support Baldinar's as he strives to recreate Aernas in his own image and gain power that would make Gods shiver. Her Special Force leader summons the demon Quoronnos as a parting gift and leaves the queen to fend for herself.
She is weakened and struggling against the demon by the time the Grand Chase reaches her chambers, but she has enough strength left to conjure a shield that protects the Chase from Quoronnos' fire breath. She then casts a barrier that negates the damage the Chase would have otherwise taken from the cursed rain that Quoronnos soon summons.
After successfully defeating Quoronnos, Gilberta thanks the Chase for their assistance but quickly informs them of Baldinar's plots to use the Aernas Hammer located in the old capital of Kounat. She lends them an airship and states that she will follow them as soon as she is healed.
Gilberta appears in Zeruel as an NPC that assists players in their fight against Quoronnos. Though she does not attack, Gilberta will constantly cast a water shield around the players that will protect them against the damaging effects of Quoronnos's cursed blood rain for 30 seconds, after which the shield dissipates.
