"Want some?" he said, proffering the cup.
Taken aback, I said yes. I'd anticipated being challenged. Who goes there? and the business end of the Kalashnikov being shoved up my nose. But a glug of hot choc went down a treat.
"Heimdall, right?" I said.
He gave a comical salute. "That's me. Watchman of the Aesir and Vanir. Guardian of the Rainbow Bridge. And you, if I'm not mistaken, are the fellow the Valkyries brought past me the other night. I must say, you're looking a lot better than you did then."
"I'm a new man."
"Good old Frigga. I wouldn't be astonished if my dear stepmother could raise the dead."
"In my case she virtually did." I liked Heimdall already. He was the most down-to-earth of anyone I'd met so far here. He made good hot chocolate, too. I held out the empty cup for seconds, and he obliged.
"So what brings you all the way out here to my humble sentry post? Mere curiosity?"
Said genially, but it was a loaded question.
"Just getting the lay of the land," I said.
Heimdall peered at me. I'd not noticed before how piercing his eyes were, or how blue. They were the icy blue of glaciers, of arctic skies. They were eyes that missed very little.
"If you're looking to leave," he said, "I must advise you, you have a considerable walk ahead."
"If I'm leaving here," I assured him, "I won't be walking."
"Sensible man."
"And you, I guess, won't be stopping me." Partly a question, mostly a statement.
"Not my job to. It's what's coming in that I have to keep an eye on, not what's going out. Would you like to see Bifrost?"
I dredged the name up from my memories of those old Mighty Thor comics. "The bridge?"
"None other. Come on."
He led me past the guardhouse, through whose open door I saw a glowing gas heater, a chair and, hanging from a hook on the wall, a long, curly trumpet-type thing made of brass.
"Its nickname may be the Rainbow Bridge," Heimdall was saying, sounding much like a museum tour guide, "but in truth it has only three colours, one for each span."
And so it did. It was a suspension bridge which traversed a deep, sheer-sided gorge in three sections divided by a pair of support towers. Its boards, scrupulously swept of snow, were painted red for the nearest section, then green, then blue. As I set foot on the first of them I heard a low, forbidding creak and felt a wobble and a bit of give, which made me step back sharpish. The drop beneath was something like a hundred metres but might have been more. Snow could make distances, especially vertical ones, hard to gauge.
"Don't worry, appearances to the contrary it's quite secure," Heimdall said. "We've had all sorts of traffic over here, even up to five-ton trucks, and Bifrost, anyway, is destined to remain standing for all eternity. After all, it's built out of fire, water and air — the three elements of creation."
Looked to me like the only materials involved were metal, timber and emulsion, but I kept shtum.
"This is the only way in or out of Asgard other than cross-country," Heimdall said, "and I couldn't recommend that. You know yourself what it can be like out there for the unwary traveller. And it isn't just wolves you have to watch out for."
"Yeah, I know. Trolls, right?"
"Or simply getting lost," he said, probably not spotting the cynicism. "Plenty of space out there to get lost in. The forests are vast and trackless. Unless you know your way around them, as the Valkyries do, you could wander there in circles 'til you die."
I gestured to the far side of the bridge. "But that-a-way, over the bridge, that'll definitely get you back to, er, Midgard. Right?"
He nodded. "Long way, though. Very long way. Bifrost is the only link between Asgard and Midgard, but many Midgardian roads lead to Bifrost and you may take the wrong one and end up far from where you'd wish to be."
"Like I said, I won't be walking. I'll — "
All at once, Heimdall's head snapped round. He squinted, eyes narrowing to glittering pinpricks.
"Did you hear that?" he whispered.
"Nope. But then I've got shit hearing."
"I haven't. Quite the opposite. I can hear wool growing on a sheep in a far-off field. I can hear a blade of grass pushing up through the soil in the next county."
"That's quite a talent. Maybe you should — "
"Shh!" he hissed. "There it is again."
He whipped the Kalashnikov off his back, switched the selector to semiauto, and racked the charging handle. His gaze was focused on the woods lying beyond the gorge. I saw him slow his breathing to the bare minimum, scarcely a trickle of vapour coming from his nostrils. He stood rigid. Only those eyes moved, scanning the gloomy darkness beneath the distant trees.
A minute passed.
Two.
I didn't say a thing. Heimdall was scamming me. There was nothing out there. He hadn't heard a sound. He just wanted to spook me, for reasons best known to him.
Only, the intensity with which he was staring…
And, I couldn't be sure, but he seemed scared. Alarmed, at any rate. Genuinely. Not faking it. There was a strain about his face, a tightness to his jaw. Whatever he'd heard, or thought he'd heard, wasn't something he'd been keen to hear.
And then it stole over me — a sense of being watched. Someone out there hiding among the trees, surveying us. A definite presence.
The hairs on the back of my neck crackled. I could see no eyes, but I could feel them. The dead weight of their gaze, looming from the shadows.
Five whole minutes passed, and then, with a "hmph," Heimdall lowered the rifle. "Yes. Well. Gone. A scouting party, sneaking around, reconnoitring. They're starting to get bold."
"Who is?" I couldn't help but ask.
"The enemy. They were well concealed, so I couldn't tell if it was frost giants, trolls, or the other enemy — the one we really have to worry about."
"Oh. So the frost giants and the trolls aren't so bad, then."
"Not to be underestimated, but a nuisance more than anything. Certainly not worth blowing the Gjallarhorn for."
I worked it out for myself. "Your trumpet? The one I just saw in the guardhouse?"
A sombre nod. "That's reserved for one very particular occasion. The day we're all dreading. The day we're preparing for but hoping will never come. When I blow the Gjallarhorn… Well, let's just say you'll wish I hadn't had to."
He left that hanging ominously in the air for a moment or so, like a bad smell. Then his mood lifted and he said, "Still, that's in the future. Now's now, eh? Cherish the moment. Speaking of which, I understand there's going to be a feast this evening. Big celebration."
"No one told me. What in aid of?"
"No special reason. Odin just likes to hold feasts every once in a while. Helps everyone get along. Cements solidarity. You should be there. They're terrific fun. All sorts of roistering goes on."
"Blimey, really? Roistering? I haven't had a good roister in, ooh, ages. You going?"
"Oh no. Never abandon my post. That's my duty and my curse as Heimdall, born of nine mothers, gatekeeper of Asgard. I'm on watch here at all hours and in all weathers. Can't relax my vigilance for a second. I did let my guard down once, you see. A long time back. Allowed a witch called Gullveig to pass. Granted, she was disguised as a beautiful maiden, but even so. Caused all sorts of bother among the Aesir, did Gullveig. They quarrelled over who could give her the most gold. Odin had to sort it out by burning her at the stake. Three times."
"Nice."
"After a slip-up like that, I've had to be extra careful, as you can imagine. So no time off, no fun and frolics for me." A tiny sigh as he said this. "But you must attend the feast. You won't regret it."
Won't regret it? I was regretting everything about the Valhalla Mission. Regretting I'd ever heard about it, regretting coming here most of all. As I followed my own deep footprints back to the castle, I mused on the fact that even the people at Asgard Hall who seemed normal at first glance, like Heimdall, weren't. Every one of them was infected with Odin's obsession, to the extent of spouting gobbets of mythology as though they were pure gospel truth.
