Tharizdun called upon messengers to announce a house party to the other gods. 19 lesser demons heeded his call, it appears as though the angels of his past are no longer. Tharizdun has been thoroughly corrupted by his time with the sword, and his death. Though he would not understand how he was changed, the very nature of his being was changed. In past he was virtuous, embodied honor and justice, and law, but now he embodied pure chaos. He was not necessarily malevolent, but morals were no longer in the equation.
The gods all answered the call. Corellon was the first to speak, taking the form of an elf wearing leather armor. "How are you alive? We all sensed your death. How long have you... been resurrected?" Tharizdun smiled at the question. "I'm about as certain of this as you are, my dear friends. But I've been... conscious for two centuries." Vecna, taking the form of a lich in black robes with blood red trim was the next to speak. "I sensed your life force five hundred years ago. It was faint, but it was distinctly what you have become." Tharizdun's mouth twitched slightly at this.
"I've called you all here for a very important reason. We must celebrate our ultimate victory of the destruction of the elemental chaos!" With that wine bottles appeared pouring their contents into glasses that all floated around each of the gods. Melora, in the form of a werebear, was the first to take a drink. She fancied herself dry red wine. She seemed a bit puzzled though, "The Primordial's still live. The elemental chaos has fallen into ruin thanks in part to the demons. The Primordials now fight simply to survive against the ravenous hordes of demons that have invaded their realm."
"You mean, I didn't destroy the elemental chaos... I merely weakened it?" His eye twitched this time. A big chunk of what had made him amenable to meeting the gods instead of hunting them down one by one was he felt they owed him a celebration of his victory. "You fools! You have squandered the gift my death provided! Now it's all... it was all for nothing!" Moradin in the form of a dwarf with a beard as black as soot was the next to speak. "Now ya' listen here! We ain't squandered nothin'! Yer sword brought upon the ultimate embodiment of chaos; demons! You were a fool ta' think you could do it alone."
Tharizdun remained completely calm externally, but mentally he was losing his grasp on reality. His preconceived ideas about himself were all wrong. He brought about ultimate chaos, but did it even matter. The gods were in charge. He could be in charge. The Primordial's no longer mattered, they were merely inconvenient. The ravings of a mad man often include delusions of grandeur, and Tharizdun was certainly mad.
Tharizdun finally centered his thoughts. The party was off. There was nothing more to celebrate, but he could still have his own personal celebration; one that included drinking the blood of his friends and ushering in a new age. Mortals beware, the age of Tharizdun was imminent. The last spark of sanity in Tharizdun reached out to his friends, "Run you fools!", but it was too late. The powder keg that was his mind was lit, and an explosion of activity occurred.
Avandra, in the form of a human in a traveling cloak was the first to be hit by a blast of pure magic. She was thrown back into a wall, and the other gods were all blasted backward. Tharizdun was beyond speaking now, his thoughts were running far faster than his mouth would be able to translate. He was beyond reason. Vecna was the first to recover, and he used a spell to teleport back to his domain. This Tharizdun could not be controlled like he had hoped. Tharizdun was too volatile, not even being able to remain civil for a party!
Asmodeus drew a magical rapier and flew on his devilish wings. A bolt of lightning struck him in the chest, causing him to drop his blade and plummet out of the air. What power was this? How could Tharizdun channel so much energy into his spells, and not even require a movement or utterance of an incantation? It seemed unreal. The gods retreated without saying much. What they needed to do was obvious, they needed to regroup and discuss how they would deal with Tharizdun. They did just that in Bahamut's domain.
A floating castle in the sky. It was quite a sight to see, but the gods were not here for sightseeing. They were here to formulate a plan. The discussions were heated; some gods were in favor of killing Tharizdun, while others still clung to their past friendship. It was difficult for them to see the monster he had become. It was simply too erratic, but also incredibly powerful. Compromise was not something that came naturally to gods, but they eventually settled on the course of action that suited everyone's best interests. They would imprison Tharizdun in a pocket dimension away from everyone, and he would be guarded by thirteen legions of angels and devils. They would erase all record of Tharizdun from the mortal realm, and Bahamut would gain the attributes of honor and justice, and Erathis would gain the attribute of law. The evil gods were not happy with the solution, but they needed a speedy resolution or be hunted down.
The gods dismissed the meeting and retreated to their individual domains for a short respite. The coming darkness was frightening to them all. There was no guarantee they would all survive. The only things the gods were certain of was their conviction. Their only hope is that Tharizdun is easy to trick.
