Gwendolyn is the player character in Tides of Annihilation. She is the sole survivor of London's destruction and the only person capable of wielding the gray fog, a power that allows her to summon and command spectral knights in battle.
Voice actor
Gwendolyn is voiced by Jennifer English, best known for playing Shadowheart in Baldur's Gate 3 and Maelle in Clair Obscur: Expedition 33. Her real-life partner, Aliona Baranova, voices the antagonist Mordred, marking the first time the two play opposing characters in the same game.
Abilities
Gwendolyn fights with a sword that is actually the shape-shifted form of her companion Niniane. Through the gray fog, she can:
Summon up to four spectral knights at once (two per set, two interchangeable sets)
Swap knights mid-combo using directional buttons
Enter a Partnered State by absorbing a knight, gaining enhanced mobility, synchronized combos, and defensive parrying
Channel elemental energy from knights into her weapons (lightning, fire, ice)
Weapons
Four weapon types are confirmed for Gwendolyn:
Swords as the primary melee weapon, provided by Niniane's transformation
Fists for close-range brawling
Bows for ranged combat
A fourth weapon type that the developers have not yet revealed
Customization
Gwendolyn's appearance can be customized through collectible armor sets, hair styles, and makeup options. Armor is purely cosmetic with no stat bonuses. The developers made this choice to keep progression skill-based rather than gear-dependent.
Motivation
Gwendolyn's goal is threefold: save her sister, restore the shattered world, and take vengeance on the demi-gods of Avalon who destroyed London. Finding scattered Grail Shards is the practical means of achieving all three objectives.
