Recently I have played a game , Dragon Age III. And I encountered some sentences in this game , which I don't understand. It 's a letter and please  explain or translate for me. Thank you .

A letter from Sera follows:

For your big-hats,

Lord whoever says you're rubbish.

His servants don't care, but could.

Drop a few things for them,

they'll give Josephine a surprise.

I think scrolls or something.

Sera

这是龙腾世纪3上面的一段话，读起来像诗歌一样，我看不懂。希望有人能帮我翻译一下，或者讲解一下这些句子。万分感谢O(∩_∩)O
