Seath is not immortal. He was immortal (or a "true undead" to be specific) due to the Primordial Crystal which the Chosen Undead destroys during the events of DaS.

Perhaps he fragmented like Manus, but the Children of Dark don't appear to be Manus, so I doubt it's really him. However, I think Freja was granted some of Seath's power, which Seath could've done while still alive either way.
