Big-hearted. A man of broad-mindedness that does not care very much about trivial matters. Greatly generous, without jealously, and doesn't know and feel fear. Humane and sincere. Even to an opponent judged to be trustworthy, Fergus has the tolerance to show and share his heaps of generosity in his first meeting with that opponent. However, he never permits betrayal, and he will not forgive one who does it, whether they are a king or not. He always keep the promises he exchanges.
