Merlin's deeds of note stretch far back into distant history, but of most relevance are the deeds he has undertaken for Logres. He is largely responsible for the rise of Uther Pendragon to power, and seems intent on ensuring that Pendragon takes the throne of the High King of England, just as Uther's brother, Aurelius Ambrosius, did before him. Their relationship has not been without contention, however, and Merlin seems to grow ever more impatient with the shortcomings of King Uther.
In [[486]], Merlin encountered [[CharactersCharacters_(Pendragon)#The Ursine Brotherhood|the Ursine Brotherhood]] for the first time. The young knights were finishing up an uneventful patrol around [[Locations#Salisbury|Salisbury]] when they were confronted by an old goat herd commanding them to go fetch [[Earl Roderick of Salisbury]]'s prized goat from on top of a hill. When the knights went off in search, they found a goat the size of a young bull which was quickly snatched by a small [[giant]]. Slaying the giant, the elderly man revealed himself to be Merlin himself, who led the knights into the forest. Eventually the knights found themselves transported into the Otherworld, where they were attacked by a [[nukalavee]] and a [[Fae hound]]. Defeating these enemies, the Ursine Brotherhood watched as Merlin took a small boat out to the center of the lake and was presented with [[Excalibur]] by the [[Lady of the Lake]] herself. Merlin thanked the knights for their protection and bade them farewell shortly after this incident.
In [[490]], Merlin helped Uther to avoid civil war by advising him on how best to deal with the difficult negotiations with the army of Cornwall. Later that same year, Merlin used his magic at the [[Battle of Lindsey]] to turn the tide in favor of King Uther's army, leading to the defeat of the armies of [[King Octa]] of the Saxons.
