Astrid, Raiden and The Twins

Astrid and the twins where helping Raiden and the others clear the rubble when Rogue suggested they took a break, they had already cleared the rubble in the hole and were standing at the entrance to the secret room with the room filled with rubble, the entrance was blocked. They would have to dig their way in. Just as they were about to walk away, Astrid heard a heartbeat coming from just above the room. She whispered to Raiden to not to alert whoever was there. Raiden, then used his telepathically, to let everyone know somebody was just above the room probably looking for the crystal. Raiden thinking about Rogue said about if they cleared all the rubble themselves they would be too tired to fight any enemies, had an idea on how to clear the rubble faster and easier so they could fight if needed. He used telepathy to call his, Astrid's, Blade's and the twins dragons as well as any wild dragon on Berk. The five dragons belonging to the main group arrived first, he then used his DNA manipulation to turn them all temporally into Whispering Deaths and had them start digging. As more wild dragons showed up, he did the same with them so the entrance never got too crowded. Now there were fifteen dragons digging out the tunnel that all would be ready to fight if needed and the others could sit, relax and rest while the dragons cleared out the room for them so once it was done, they'd all be ready.
