Mithril Platelegs

Would Dowdun Reach be standing without mithril? At the very least, it would be standing elsewhere. And since 'elsewhere' would put it in the path of dragons, the Withering and Saradominists at various points on Ashenfall's timeline, you would have to surmise that no, Dowdun Reach would not exist.

There was a time, before the Withering, when a choice was made. The Children of Shadows became paranoid about the prospect of attack and betrayal. It did not seem to matter that they were guarded by dragons who manufactured peace. Dark whispers moved them to act.
