After resting sufficiently, the group prepared to enter the fourth level.
They approached the now-familiar blue crystal. With a shared nod, they reached out and touched its smooth surface.
In a dizzying flash of light, they found themselves transported to a new chamber. The cavern walls shimmered with an otherworldly glow, casting long shadows across the rocky floor.
As in previous levels, a new emblem awaited them: the Emblem of the Wall.
Following their newly established tradition, they chose the bearer at random from those who still didn't have an emblem.
The winner stepped forward, heart pounding, and activated the artifact.
"My defense... it's doubled," he murmured, awe evident in his voice as he felt the power coursing through him.
The others nodded, recognizing the value of the new emblem. Yet, they couldn't help but feel a twinge of envy towards the bearer of the Emblem of Power.
