A mystic helmet worn by the legendary Immortal Knight. It spurs the wearer to continue fighting.

I abandoned my name and my life to serve Azema in this helm.
Now, it has chosen you.
May you use its power for all of Ulos, united as one.
-Anonymous, inscribed inside the Immortal Helm

The helm is imbued with power to allow the wearer to travel between planes. Some believe that it also may grant the secret of immortality. They would be wrong.

Searching the endless stacks of the Klynoks, you find a durgolium chest. Opening it, you discover the Immortal Helm. Taking it, you sense that it will somehow lead you home.

You will have the opportunity to place the Immortal Helm on your own head. Doing so will convey the title of Immortal Knight to you. Along with the title, your mind is flooded with visions of past knights. Their knowledge and power are now yours.

“Put on that helm. You’ve earned it. Nalos will be honored to be served by such a selfless Immortal Knight.” - Tarik Nowlin - Above the Dreaming Sea (RPA-ADV10)

After the battle at Nebblis, Plane of Flame, King Taron comments on your wearing of the Immortal Helm;

“You handle yourself well in battle. We of Nalos are lucky to have you. Did Tarik tell you about the…” King Taron cuts himself short, pointing at the side of your helm. “….well, never mind,” he says. “You’ll discover its secrets soon enough, I’m sure.” - Gate of Brizoor Waal (RPA-ADVF)

Following the events at Brizoor Waal, a navigational system seems to have activated about the Immortal Helm;

Ever since the gate opened, the Immortal Helm has been acting strangely. It makes noises at times and projects odd images into your eye when you wear it. You guess these are maps, perhaps maps of the planes and their connections, but none of the paths it suggests leads to Brizoor Waal. Instead there are little shifting pockets of activity all over Nalos where a link might be made to some other place. When time and safety permit, you may explore one of these sites and see where it takes you. - Gate of Brizoor Waal (RPA-ADVF)

The Klynoks will allow you to purchase the helm from them, possibly at a discount if you are in good relations with them. You may also be able to trade for all the armaments of the Immortal Knight.

“This is not just any red helm. This is THE Red Helm of the Immortal Knight. He’s been here. And without this, he may need our help.” - Tarik Nowlin - Silver Threads of Fate (LC1)
