Bel's Encounter.
"What's going on?" Ossa sat on the ground confused. He had stumbled so hard that he fell on his pelvis, confusion vivid in his eyes.
" Huh..." He rose to his feet, got closer to where he felt the invincible wall, and gently touched it, trying to feel for the strange barrier.
" An invisible wall," He thought as his hand could not move past a particular point, his hand touching a wall which was tangible but not visible.
The strange invisible barrier seemed to start from the point where the clearing around the water body began.
" Mors?!" Internally he called out to the system as it was strange he could not see the barrier.
Even though he saw things just as humans did, he also had other forms of vision that human retinas were incapable of perceiving since their retinas needed light to function.
He, as a creature born of soul energy, a form of pure mana, could perceive different types of mana.
