On Tarsakh the 13th, the trance of your normal meditation is disturbed as you enter an unnerving dream.
In the dream, you are in a vast cavern, the heights of which you do not perceive. You hear clicking sounds, and upon looking around realize you are surrounded by massive spiders. They notice you and immediately close in, segmented eyes staring coldly and their fangs quivering threateningly. Surrounded, and filled with fear, you begin to run - barely evading their grasps but never quite outrunning their tireless hunt. Suddenly you spot a distant light source, and hastily make your way towards it. However, the way is filled with obstacles and the footing is rough, and many times you are almost caught by your tenacious pursuers.
Horrified and panicked, you lose your focus and trip over the treacherous terrain. Just as despair fills you, you realize that you've the reached the light source - a vague object shrouded in green flame. As you reach out and grasp it, the flames spread down your arm and engulf your body. You feel empowered, and the arachnids now shrink back from your illuminated form. Filled with dread might you begin to grow until your colossal size dwarfs your once horrendous predators.
Laughing malevolently, you crush the fleeing spiders beneath your heel.
