[ Loki takes a moment to shoot Thor a dark look. ]

From what I can tell, your power seems to derive from stories. A world of stories if killing a dragon opens a portal. However, having not seen it work here or in person, there's little else I can do. I have given you my expertise and told you what I know.

So, again, I'm not entirely sure what you expect me to do. You wish to take the risk. If that is how you feel, there's little else I can say.
