'Being over the edge of the world' itself had little to do with the disaster.
Explanation:
<u>In "the Hobbit' the allegory of being over the edge of the world is about the adventure being completely off the charts</u> and never having been something like that before, which was of course untrue.
But for the characters concerned, it indeed was true.
Characters with Beowolf like characteristics would be well prepared for a disaster because in a way they signed up for it.
<u>Smaug and other figures of 'disaster' are prophecised as a part of the journey.</u>
Present perfect tense. Have washed is the verb, Have or Has is used to show an action that has taken place in the present, not quite long or is still taking place
