Sekkendin was a male bushy watervole. He lived under the hill by the river with Krobzy, Prethil, and a group of watervoles and fieldvoles. Everybody called him "Sekkendin", because he was a second-in-command member of the tribe. After Tagg visited their tribe, Sekkendin and Krobzy saw him off, giving him a coracle and cloak.
While spying on a group of Juskazann, Sekkendin was spotted and shot by Vallug Bowbeast. The wound was not fatal, but Krobzy avenged him anyway, killing Vallug's compatriot Milkeye as payback. Sekkendin was a minor character, so nothing else is known.
