Rules were made to be broken, so the adage goes. But what about vows? A vow should never be broken — but observe how far they'll sometimes bend…

The snow was falling harder now. Kassianos' mule, a good stubborn beast, kept slogging forward until it came to a drift that reached its belly. Then it stopped, looking reproachfully back over its shoulder at the priest.

"Oh, very well," he said, as if it could understand. "This must be as Phos wills. That town the herder spoke of can't be far ahead. We'll lay over in — what did he call it? — Develtos till the weather gets better. Are you satisfied, beast?"

The mule snorted and pressed ahead. Maybe it did understand, Kassianos thought. He had done enough talking at it, this past month on the road. He loved to talk, and had not had many people to talk to. Back in Videssos the city, his clerical colleagues told him he was mad to set out for Opsikion so late in the year. He hadn't listened; that wasn't nearly so much fun as talking.

"Unfortunately, they were right," he said. This time, the mule paid him no attention. It had reached the same conclusion a long time ago.

The wind howled out of the north. Kassianos drew his blue robe more tightly about himself, not that that did much good. Because the road from the capital of the Empire to Opsikion ran south of the Paristrian mountains, he had assumed they would shield him from the worst of the weather. Maybe they did. If so, though, the provinces on the other side of the mountains had winters straight from the ice of Skotos' hell.

Where was he? For that matter, where was the road? When it ran between leaf-bare trees, it had been easy enough to follow. Now, in more open country, the pesky thing had disappeared. In better weather, that would only have been a nuisance (in better weather, Kassianos reminded himself, it wouldn't have happened). In this blizzard, it was becoming serious. If he went by Develtos, he might freeze before he could find shelter.

He tugged on the reins. The mule positively scowled at him: what was he doing, halting in the cold middle of nowhere? "I need to find the town," he explained. The mule did not look convinced.

He paused a moment in thought. He had never been to Develtos, had nothing from it with him. That made worthless most of the simpler spells of finding he knew.

He thought of one that might serve, then promptly rejected it: it involved keeping a candle lit for half an hour straight. "Not bloody likely, I'm afraid," he said.

He thought some more, then laughed out loud. "As inelegant an application of the law of similarity as ever there was," he declared, "but it will serve. Like does call to like."

He dismounted, tied the mule's reins to a bush so it would not wander off while he was incanting. Then, after suitable prayers and passes, he undid his robe and pissed — quickly, because it was very cold.

His urine did not just form a puddle between his feet. Instead, impelled by his magic, it drew a steaming line in the snow toward more like itself, and thus, indirectly, toward the people who made it.

"That way, eh?" Kassianos said, eyeing the direction of the line. "I might have known the wind would make me drift south of where I should be." He climbed back onto his mule, urged it forward. It went eagerly, as if it sensed he knew where he was going again.

Sure enough, not a quarter of an hour later the priest saw the walls of Develtos looming tall and dark through the driving snow. He had to ride around a fair part of the circuit before he came to a gate. It was closed and barred. He shouted. Nothing happened. He shouted again, louder.

After a couple of minutes, a peephole opened. "Who ye be?" the man inside called, his accent rustic. "Show yerself to me and give me your name."

"I am Kassianos, eastbound from Videssos the city," the priest answered. He rode a couple of steps closer, lowered his hood so the guard could see not only his blue robe but also his shaven head. "May I have shelter before I am too far gone to need it?"

He did not hear anyone moving to unlatch the gate. Instead, the sentry asked sharply, "Just the one of you there?"

"Only myself. In Phos' holy name I swear it." Kassianos understood the gate-guard's caution. Winter could easily make a bandit band desperate enough to try to take a walled town, and falling snow give them the chance to approach unobserved. A quick rush once the gate was open, and who could say what horrors would follow?

But Kassianos must have convinced the guardsman. "We'll have you inside in a minute, holy sir." The fellow's voice grew muffled as he turned his face away from the peephole. "Come on, Phostis, Evagrios, give me a hand with this bloody bar." Kassianos heard it scrape against the iron-faced timbers of the gate.

One of the valves swung inward. The priest dug his heels into the mule's flanks. It trotted into Develtos. The sentries closed the gate after it, shoved the bar back into place. "Thank you, gentlemen," Kassianos said sincerely.

"Aye, you're about this far from being a snowman, aren't you, holy sir?" said the guard who had been at the peephole. Now Kassianos could see more of him than a suspicious eyeball: he was short and lean, with a knitted wool cap on his head and a sheepskin jacket closed tight over a chainmail shirt. His bow was a hunter's weapon, not a soldier's. He was, in other words, a typical small-town guardsman.

"Want I should take you to Branas' tavern, holy sir, let you warm yourself up outside and in?" asked one of the other guards. But for a back-and-breast of boiled leather and a light spear in place of a bow, he was as like the first as two peas in a pod. He glanced toward that man, who was evidently his superior.

"Is it all right, Tzitas?"

"Aye, go on, Phostis, we'll manage here." Tzitas showed his teeth in a knowing grin. "Just don't spend too much time warming yourself up in there."

"Wouldn't think of it," Phostis said righteously.

"No, you wouldn't; you'd do it," said Evagrios, who'd been quiet till then. Tzitas snorted.

Phostis sent them both a rude gesture. He turned back to the priest. "You come with me, holy sir. Pay these scoffers no mind." He started off down the street. His boots left pockmarks in the snow. Still on muleback, Kassianos followed.

The tavern was less than a hundred yards away. (Nothing in Develtos, come to that, looked to be more than a quarter mile from anything else. The town barely rated a wall.) In that short journey, though, Phostis asked Kassianos about Videssos the city four different times, and told him twice of some distant cousin who had gone there to seek his fortune. "He must have found it, too," Phostis said wistfully, "for he never came back no more."

He might have starved trying, Kassianos thought, but the priest was too kind to say that out loud. Videssos' capital drew the restless and ambitious from all over the Empire, and in such fast company not all could flourish.

Even with Phostis', "Here we are, holy sir," Kassianos could have guessed which building was Branas' from the number of horses and donkeys tied up in front of it. He found space at the rail for his mule, then went in after the sentry.

He shut the door behind him so none of the blessed heat inside would escape. A few quick steps brought him to the fireplace. He sighed in pure animal pleasure as the warmth began driving the ice from his bones. When he put a hand to his face, he discovered he could feel the tip of his nose again. He'd almost forgotten he still owned it.

After roasting a bit longer in front of the flames, Kassianos felt restored enough to find a stool at a table close by. A barmaid came over, looked him up and down. "What'll it be?" she asked, matter-of-fact as if he were carpenter rather than priest.
