When Luke was preparing to go to the dark elves' world' Danielle and Sylah showed up the next day. While they couldn't help much since Luke was thinking of raising the strength of the skeletons, they still wanted to go. After thinking for a while, Luke realized that it wasn't a good idea to leave those two at home. They might sneak out again... with them, he will be able to keep an eye on them since their goal would be the same for the time being. Besides, they were pretty strong since they managed to stay in the world without suffering a single scratch.
"All right, you guys can come, but no sneaking around and going without us," Luke said. "The next time that happens, I will really make you all eat broccoli three times a day."
