Jagfang was a male searat who fought against Skipper Sterling Firhound's Rogue Crew. He survived the battle, though just barely, having been stabbed in the stomach. He was found by other vermin, under the command of the weasel captain Magnus Clawford.
He had been hidden in the saltgrass while the otters discussed their plans among the carnage, and was able to tell Magnus everything he knew before the weasel drove his cutlass into his gut, in order to secure full credit of the otters' executions.
Hit once more by a cutlass thrust, it was obvious Jagfang's luck wouldn't hold out a second time.
Magnus wiped his cutlass on the dead rat's body, telling his rather shocked crew that they would be well rewarded after all of their problems were done. This seemed to cheer them up immensely.
