They could stand around discussing things as much as they wanted, but there some things that waited for no one. the wards Zeus and Isis had placed were stopgaps to begin with, and the slow, fateful ruin of the bindings around the ancient god took the decisions out of the hands of the other Theoi. It started as a small crack along the bottom of the sarcophagus, opening into an ever-growing chasm as it traveled its way up, the crackling of the old stone faint yet deafening as it sounded in the room. There was a moment of silence, then a crash as the front disintegrated, revealing to the room the dusty confines of the coffin. At first glance there was nothing inside save a decayed skeleton and canopic-style jars, but the sudden presence in the room was more than enough to let the Theoi know there was a newly awakened among them.
Yet only the emotional half of the god was released, his logical side still trapped where it was, and what was free was not pleased. The room filled with sound as the disembodied Theoi roared, his mind lashing out at any unwarded mind in the room. A slow steady whirlwind swept through the exhibit, pulling matter towards the center where the now broken sarcophagus stood.
[OOC: if you have Mind 2 or higher, you can ward yourself from the mind attack. If you have Mind 4, you can ward others as well. if you have no mind, and no one with mind wards you, imagine a sudden, shrieky migraine that's penetrating thoughts and concentration - like a mental scream. Granted, even those with mind will be taking some damage in the time it takes to block it... and it hurts. ]
