Everything happened so quickly that Yale didn't have any time to react until the group had been swallowed by a space ripple.
Besides his friends, most of the members of the Dragon Race that had been hiding in the Storage Space had been swallowed.
Of course, being swallowed wasn't equivalent to death because it would depend upon luck.
If they managed to appear in a place without merging with the environment due to the random teleportation, they would probably be fine as long as there wasn't any powerful enemy nearby. However, the chances of all of them having that luck were almost inexistent, and that would be considered a miracle; Yale couldn't believe that they were all alright.
