After 3 full years of living inside the cave and having every possible sense taken from him , Ronan lived the last 3 months of his tenure simulating a near dead state.
Devoid of any sense at all , Ronan was forcefully bedridden . He could not sleep due to the nightmares but his eyes had no more light inside them to distinguish day from night after he gave up his vision.
With nothing but his brain functioning , Ronan was just a slab of meat , passing time without knowing when his suffering would end. However the last 3 months saw him develop the most terrifying natural skill of them all as he discovered the secrets of his own body.
Although he could not see , Ronan could visualize the internal structure of his very own body and feel every mana vein clearly and the mobilization of elemental energy in his own body's pathways.
