What is the Seeker in Guild Wars 3?

The Seeker is the player's companion creature. The press release describes it as both a connection to the spirits of Orr and a mount, tied to the Vaelwarden role you play.

Can you fly in Guild Wars 3?

Gliding is confirmed as part of the momentum movement system, alongside riding, leaping, and wall running. Free flight or flying mounts are not confirmed.

Guild Wars 3 mounts

Short answer: one mount is confirmed. Every player has a Seeker, which ArenaNet calls both a connection to the spirits of Orr and a mount. Anything beyond that is not announced.

The Seeker

The announcement press release confirms each player has a Seeker, described as both a connection to the spirits of Orr and a mount. That double role matters: it ties your mount to the Vaelwarden, the guardian of Orr you play, rather than making it a stable of interchangeable animals. ArenaNet has not said whether the Seeker takes different forms, how you get it, or whether other mounts exist alongside it.

Mounts inside the movement system

Riding is one mode in a larger system. The official site describes movement that "transfers your momentum between modes of travel," chaining gliding, riding, leaping, and wall running. The full picture is on the gameplay page. Momentum even feeds into combat, which rewards movement alongside skill use and positioning.

How Guild Wars 2 set the bar

Guild Wars 2 added mounts in the Path of Fire expansion in 2017, and they were widely praised for being movement abilities rather than speed boosts: the raptor leaps, the springer jumps high, the skimmer hovers, the griffon dives. The Seeker plus momentum movement reads like the next step of that design lineage, though that read is ours, not ArenaNet's.

The honest take

Confirmed: the Seeker exists, it is a mount, and riding chains into gliding, leaping, and wall running. Not confirmed: additional mounts, flying, customization, or how the Seeker grows. Everything official lands on what we know as ArenaNet reveals it.
