Although Stannis suffers from a lack of support and resources during the War of Five Kings, he is frequently described by his adversaries, including Tywin Lannister, as the most dangerous rival claimant. Above all he is characterized by his fearless and uncompromising pursuit of justice and duty - he is described by Varys in this way: "His claim is the true one, he is known for his prowess as a battle commander, and he is utterly without mercy. There is no creature on earth half so terrifying as a truly just man."
