Paran was silent for a moment, thoughtful, then he said, 'Go on.'

'Us Bridgeburners, we got work ahead of us, and some of us don't like it. I mean, we're dead, right? And sure, it's good helping friends who are still alive, and maybe helping all of humanity if it comes to that and I'm sorry to say, it will come to that. Still,you end up with questions, questions that can't be answered.'

'Such as?'

The sapper's expression twisted. 'Damn, sounds awful, but… what's in it for us? We find ourselves in an army of the dead in a damned sea where there used to be desert. We're all done with our wars, the fighting's over, and now it looks like we're having to march – and it' s a long march, longer than you'd think possible. But it's our road, now, isn't it?'

'And where does it lead, Hedge?'

He shook his head again. 'What's it mean to die? What's it mean to ascend? It's not like we're gonna gather ten thousand worshippers among the living, is it? I mean, the only thing us dead soldiers got in common is that none of us was good enough or lucky enough to survive the fight. We're a host of failures.' He barked a laugh. 'I better remember that one for the bastards. Just to get under their skins.'

Paran glanced back at the carriage. Still no activity there, although the servant had disappeared back inside. He sighed. 'Ascendants, Hedge. Not an easy role to explain – in fact, I've yet to find a worthwhile explanation for what ascendancy is – among all the scholarly tracts I've pored through in Darujhistan's libraries and archives. So, I've had to come up with my own theory.'

'Let's hear it, Captain.'

'All right, we'll start with this. Ascendants who find worshippers become gods, and that binding goes both ways. Ascendants without worshippers are, in a sense, unchained. Unaligned, in the language of the Deck of Dragons. Now, gods who once had worshippers but don't have them any more are still ascendant, but effectively emasculated, and they remain so unless the worship is somehow renewed. For the Elder Gods, that means the spilling of blood on hallowed or once-hallowed ground. For the more primitive spirits and the like, it could be as simple as the recollection or rediscovery of their name, or some other form of awakening. Mind you, none of that matters if the ascendant in question has been well and truly annihilated.

'So, to backtrack slightly, ascendants, whether gods or not, seem to possess some form of power. Maybe sorcery, maybe personality, maybe something else. And what that seems to mean is, they possess an unusual degree of efficacy-'

'Of what?'

'They're trouble if you mess with them, is what I'm saying. A mortal man punches someone and maybe breaks the victim's nose. An ascendant punches someone and they go through a wall. Now, I don't mean that literally – although that's sometimes the case. Not necessarily physical strength, but strength of will. When an ascendant acts, ripples run through… everything. And that's what makes them so dangerous. For example, before Fener's expulsion, Treach was a First Hero, an old name for an ascendant, and that's all he was. Spent most of his time either battling other First Heroes, or, towards the end, wandering around in his Soletaken form. If nothing untoward had happened, to Treach in that form, his ascendancy would have eventually vanished, lost in the primitive bestial mind of an oversized tiger.

But something untoward did happen – actually, two things. Fener's expulsion, and Treach's unusual death. And with those two events, everything changed.'

'All right,' Hedge said, 'that's all just fine. When are you getting to your theory, Captain?'

'Every mountain has a peak, Hedge, and throughout history there have been mountains and mountains – more than we could imagine, I suspect – mountains of humanity, of Jaghut, of T'lan Imass, of Eres'al, Barghast, Trell, and so on. Not just mountains, but whole ranges. I believe ascendancy is a natural phenomenon, an inevitable law of probability. Take a mass of people, anywhere, any kind, and eventually enough pressure will build and a mountain will rise, and it will have a peak. Which is why so many ascendants become gods – after the passing of generations, the great hero's name becomes sacred, representative of some long-lost golden age, and so it goes.'

'So if I understand you, Captain – and I admit, it's not easy and it's never been easy – there's too much pressure these days and because of that there's too many ascendants, and things are getting hairy.'

Paran shrugged. 'It might feel that way. It probably always does. But these things shake themselves out, eventually. Mountains collide, peaks fall, are forgotten, crumble to dust.'
