Deyna

Deyna was the son of Rillflag and Filorn, brother of Mhera, and ancestor of the Skipper in Triss. He was born with a birthmark on his pawpad in the shape of a speedwell flower. As Rillflag's ancestor had also been named Deyna, the young otter was also given that name. As a babe he was kidnapped by Sawney Rath, whose seer Grissoul had predicted that the new Taggerung would be a creature of Redwall Abbey.

As the young otter grew up in the vermin camp, he began to feel as though he didn't belong. Finally, after an argument with Sawney, Deyna (or Tagg, as he was known) left the Juska camp for good. During his journey, Tagg met a young harvest mouse named Nimbalo. The two stopped at the colony of a tribe of pygmy shrews, and stayed there until it was attacked by vermin. Tagg rushed out to confront the vermin, and they ran away. The otter did catch Ribrow, however, who told him of his past and how he came from the Abbey. And so, Tagg finally returned to Redwall and was reunited with his sister and mother. After that took up the sword of Martin and was made the Abbey Warrior.

In order to stop the marking on his pawpad from causing further trouble in his life, Tagg had both it and his Juska tattoos removed by Rukky Garge, a legendary otterfixer.

Ruggan Bor, a fox who had taken over the Juska, came to Redwall in the hopes of conquering it and killing Tagg, but he was stopped by Russano the badgerlord, who had come to the Abbey informed by a vision of Lady Cregga Rose Eyes.

Deyna is an extremely competent warrior. He spent most of his youth being trained in the ways of war by Sawneys tribe. In time he became a peerless tracker and master of many forms of combat; on one occasion disabling an assailant despite being bound paw and foot. However Deyna is far from violent and his strong morals prevent him from taking life; this puts him at odds with his adoptive father who realises that Deyna will never become the merciless living weapon Sawney wanted him to be. While he respects Sawney as a leader Deyna is disgusted by his master's ruthlessness which eventually leads him to desert the tribe. Deyna was also the first otter to be Abbey Warrior.

Skipper of Otters and Master of Arms at Redwall Abbey in Triss is a direct descendant of Deyna. He also seems to have inherited some of his skills.

Etymology?
In keeping with his predicted destiny, Deyna's name may be derived from the Welsh deyrnas, which means "kingdom" or "realm."
