(a little more than a sentence for you... ;) )
Deep in Ashenvale, whether on the wind or in demons' whispers, the spirit of Grom called to him. Dilated and wide, his pupils vibrated with surmounting madness, the voice of his father drowning out the Warsong. It was close. It lingered. Something, someone, some energy, channeled itself into him with claws and tendrils and thousands of eyes with lashes like daggers. Rivers of blood once spilled from Mannoroth pulsed in the soil beneath him, a grueling heartbeat under his feet, tasting the smoke and charred flesh of the demon's presence.
"Son of Grom! Son of Grom!"
"The demon's fire," Grommash croaked, "has burnt out in my veins..." His immortal words thundered in his son's head. The midnight soil spoke. "The fire... in my veins..."
As another set of eyes within his mind, a spirit, he saw Thrall, younger than now, knelt by the body of Grom. "No, old friend..."
"The fire... the fire..."
Booming and rattling, the pit lord's words resounded. "He didn't know what burns within your soul... when in your heart, you know we are the same."
This was not the reproduction Thrall had displayed in Garadar. This vision was the contribution of hundreds of the eyes and beating hearts of witnesses, and he still heard them beating, and he still heard the wet eyes rolling in their sockets. They lived, somehow, still, his mind trapped in their skulls.
