So, you're not trying to get the source of a Wikia page, you want to write a script on Wikia to load that runescape.com page and display it?

You would need to use javascript to do that.

Edit: I imagine that some wikis may have already implemented similar scripts, so you might want to look around before writing your own from scratch.
