Good story. It's making me cry, though.

Excellent story. It was very descriptive.

And perhaps the greatest irony there is that another reach for success by a Selkie came to failure in Conall Curach.

I like that you don't call it the marsh of dead dreams until the end, drawing the irony and sadness through the entire piece. That Raem would consider De Nam a threat to his dominion and order his minions is a great concept, I'd never considered that Raem would take such an active part in the realm.

That only the ghost and Raem actually spoke, whereas the other monsters did things to convey their thoughts was a good point on which creatures had "souls" per say. Much better than having all of them talk.

De Nam's fight was done well. I like that you had him fight back, though if you ever write another story about De Nam's death maybe you could have him fumble a bit or get frightened at first. He seems to have been a scientist first and a fighter second, only defending himself so that he could do field studies. As a character he's probably less used to the way of the warrior than a caravan member.

Nice syntax, by the way. I like the sentence variety.

Continuity point, I don't think his breath would be a whisper on the wind if he drowned, unless he floated back up to the surface. Or maybe I misunderstood and he died of something else? If it's the latter you might consider clarifying.

Personally, I liked it. Great job!
