As the party moved down the long hallway to the Iced over doorway, the healers healed until once again everyone was back to max health. Then the door was in front of them covered in thick ice. No one could say that Ulthok had not made sure to keep the room closed till the party could deal with it.
For the next few minutes idea's were tossed back and forth, fire, the use of axes, and other possibly chancy ways to clear the ice away. Finally once more it was the Halfling Thief/Mage that came up with a party agreed upon idea.
"I'm going to cast Shatter. It will center about 3 feet inside the doorway in the ice. Seeing that ice is a crystal of water it may work to break the ice into chunks that can be more easily moved or melted. The amplified magic could actually pulverize the ice. Stand back and be ready to shield yourself in case it bows back this way."
Sirene standing quietly alongside Ulthok as he began to cast reached out a ringed hand, readying magic of her own. Her thinking if the halfling's plan did work, perhaps the aid of buffeting winds might keep the shards of ice away from them. The party would thank her forethought as Ulthok uttering the words sent the spell into the ice.
At once the spell intensified three fold blew the ice apart, sending large shrapnel sized pieces flying everywhere. Hitting the stone walls those same pieces ricocheting towards the party only to hit Sirene's gust of wind and were turned back towards the door. The force of the blast though harmless still forced a few members to their knees, but no injuries were sustained.
With the doorway now open the party headed into the 50x50 circular room and as they entered they could easily frozen pieces of bloody body parts everywhere. The body parts both severed and crushed there was no way identify who or what they had once been.
However every ones eyes were at quickly drawn to the center of the room where a huge reddish gem, untouched by blood or ice, pulsated in-closed in a crystal globe, the gem at its center. Held in place in a spider web type wired frame above a pool of dark, now frozen water, bursts of electrical flashes coming quickly at random.
Could this be the flying castles power source, the way to destroy this ugly Githyanki creation and save the fortress of Craggian Core below.
