No Evidence Needed

Dís disliked Bard from the first time she saw him. Unfortunately they needed him. And fortunately he needed their money.
So now they were stuck on this little boat, listening to stories of greatness of Laketown… before the dragon came.
Bard was certain of one thing. Everybody was.
The reason why the dragon came.
It was because of the dwarves.
It was their fault. Their crime was greed.
(And that coming from the man who took nearly all their money.)
Guilty without a process.
And if that was not enough…
He stuck them into barrels and buried them in fish.
