Séarl has been tasked with gathering food for the Avanc-lûth. He personally does not have a taste for toad-legs, but that is what has been demanded by the Elders.
'Since you seem to be doing Alun's labour, then you can help me, as well. I am not certain what I did to upset the Elders, but they always give me the worst tasks.
'They want me to gather food -- which is what I am accustomed to -- but toad-legs? Toads are disgusting creatures and make even worse food. Nevertheless, it is what they demand.
'If you are to be of help, go hunt toads and take their legs. Bring them back to me, and perhaps I will not think of you as the bog-scum you are.'
Toads are all around the camp-fire where Séarl is encamped in the Dunbog.
Séarl has asked you to fetch toad-legs for him.
