Iriviel, Chloe, and Shirou first surfaced on field of snow.

Chloe: "Brr, it's so cold here!" As the cold air made contact with her exposed skin.

Shirou: "I told you that combat outfit won't protect much of you, maybe now you realize that." He disliked how she wore a modified feminized version of his own outfit and that it reduced into capturing the eyes of lolicons instead of protecting the wearer.

Irisviel: "Let's unpack our coats before you catch a cold." She was fine with the cold since she was used to it.

Soon Kiritsugu and Illya arrived with another present Zelretch dropped for them.

Zelretch: Congrats on saving many civilians during the short alien invasion. Had quite the laughter that Illyasviel became the Heroine of Japan and now many young girls want to become a Mahou Shoujo. Anyway, your next trial is survival/adventure. This land is part of Norse Mythology and they don't take too kindly with newcomers, especially foreign divine beings. There should be an abandon cabin nearby.
P.S. Here's a magic bag that can hold many small items. Free of charge since these lands contain many old relic and treasure you may find.

Kiritsugu: "So we're in the Age of the Gods, where Norse are common in this land."

Shirou: "First let's secure a cabin and bounded field before we plan our next course of action."

The cabin they found was old, dusty, and covered in snow. It took Shirou some time to get the place mostly cleaned up before getting a better look at the place. The log cabin seemed able to house for three people before it was abandoned. There wasn't anything of much value left behind, but that didn't matter. Two medium sized beds, leftover animal skin, couple of wooden chairs, round table, and few dirty pots.
Irisviel began setting up a bounded field to conceal their presence from any unwanted guest. Kiritsugu began to scout the area around them and planning to make traps once he gather necessary material. Illya and Chloe were put into cleaning the rest of the cabin, checking the beds, and starting a controlled fire to warm up the house.

Soon the earth shook, catching everyone's attention.

Illya: "An earthquake!?"

Irisviel: "Illya! Chloe!" She hurriedly went to check on them.

Shirou jumped on top of the house to find anything that may cause the earthquake, if not then it was the natural earthquake. In the far distance he could see a the head of giant snake, but it soon lowered and out of sight.

Kiritsugu: "Report."

Shirou: "It's a very large snake, my guess it could be the Midgard World Serpent from Old Norse."

Kiritsugu: "How far and will it come an threat to us?"

Shirou: "Quite a distance, around 10 miles or so. If I recall, the Serpent has a hatred rival with Thor, god of thunder, so he may not care or ignore Irisviel."

After settling down after the incident, the cabin was now livable. There was still a few things the cabin may need and other necessities they will need to gather. Maintaining and improving security is Kiritsugu self appointed job. Irisviel and Illya don't have much to do beside fueling the bounded field. Shirou plans to head out and hunt for ingredent before Kuro notices.

Chloe: "You're not planning to leave me behind were you?" Walking behind Shirou's back.

Shirou: "..." *sigh* "You're coming along no matter what I say." Rubbing his head to ease his mental pain.

Chloe: "Yep~ Onii-chan know me so well~"

[Hunting]

Traveling down the road, searching for any animal footprints to follow. Using the tall mountain as a visual land mark since they didn't have a map. Suddenly a small number of Draugr appear. Shirou and Kuro quickly traced Kanshou and Bakuya in a ready stance.

Chloe: "What are these?!" Ready to slash at the closest enemy.

Shirou: "They're..." Getting a glance at their bladed weapons, "Draugr, an undead that will attack anyone it meets."

Chloe: "Great, zombies are real. Illya would run away into mama's bosom."

The two archer Servants spring into action with their dual swords. These Draugr don't have much mental capacity as they follow their instinct to swing their weapon at Chloe. She quickly jump over the attacking Draugr and x-cross slash from behind. Shirou was tall so he could easily chop their head with the sharpness of a Rank C Noble Phantasm. It didn't take them 30 second to defeat 8 Draugr.

Chloe: "That was easy." Letting her weapon disappear.

Shirou: "Yes, but I'm sure will be seeing them a bunch more later."

After that they continue to head toward the base of the mountain, picking up any safe-to-eat berries and herbs. But as little did they know, a weird-colored Raven was watching them from its tree branch.

[Foothills]

Shirou: "I see a smoke ahead."

Chloe: "I hope is isn't more fire-shooting Draugr, they're so annoying." Recalling meeting packs of different types of Draugr. The Heavy Draugr was a joke, even Angra Mainyu could defeat it without difficulty despite being the weakest Servant in Chaldea. Suicidal bomb Draugr can be taken down with one or two sword-arrow shots. Fire throwing Draugr were too easy to defeat but they like to keep their distance or appear in high advantage points. Speed Draugr were fast but fighting against Servants with high reaction-speed or high rank agility, they will die quickly.

Entering a open-wide rock surface, there was a open wide tent, controlled fire in a bowl stand, long table in the open with tools, and a rotating wheel. There was a person with with yellowish shiny armor working on something.

Chloe: "A blacksmith?"

Shirou: "Seems so"

Chloe walked up to the Blacksmith's territory with Shirou right behind her. "Hello"

?: "Oh, welcome. I guess people are starting to come out of their shells."

Chloe: "Are you the only blacksmith around?"

?: "Yes, are you here to look at my wares?"

Chloe: "Sure, why not. My name is Chloe von Einzbern and the tall guy is Big Brother Shirou."

Sindri: "Name's Sindri. What would you like to see?"

Chloe: "Swords, I would like to see every bladed weapon you got."

Sindri displayed his creations to the both of them. Shirou scan-trace every sword, axe, and spear copied and stored in his Unlimited Blade Works Reality Marble. These weapons were better quality than most human Blacksmiths and few these had magic properties like a mystic code.

Sindri:"The handle is make from oak to keep away the little beasties."

Chloe: "Ok, but seem like none of them are up to par with our current swords." While she may speak the truth, it all hurt the pride of a blacksmith.

Sindri: "That's harsh to say, little lady. Mind showing me your sword?"

Chloe looked at Shirou and stood there for a few second thinking. Showing his blades to a blacksmith dwarf shouldn't be a problem, hopefully.

Shirou: "Trace on." Kanshou and Bakuya appear in his hand and he held them out for Sindri.

Sindri: "Such a marvelous creation..." Taking a closer look and temporary forgetting his fear of germs, "I have never seen this kind of metal."

Chloe: "It's a one of a kind twin blades."

Sindri: "Mind if I make some improvements on it?"

Chloe: "Sure, it's no problem, right Onii-chan." Shirou have a nod.

Sindri: "Just place it here and I'll begin my work."

Shirou placed down Kanshou and Bakuya and Sindri took out a scrubber. The scrubber seemed ordinary till Sindri started scrubbing Kanshou. Small specks of white light appeared then lightly wrapped the blade around. The same thing happened to Bakuya when Sindri scrubbed it.
Shirou picked up and analyzed it. What Sindri did was a small yet impressive improvement with scrubbing alone. Kanshou and Bakuya's neural circuits we're cleaned thoroughly to allow smoother flow of mana. This allowed him to reinforce his blades more efficiently and pushing their limits a bit further.

Shirou: "Thank you for the improvement, how much I owe?"

Opening the magic bag that contain useless yet money value items dropped from killed enemies and picked up from fallen travelers or knights. Exchanging junk for money and resources.

Chloe: "Happy making bushiness with you, but we got to go."

[Forest]

Heading back on the road, they finally found a deer. Shirou pulled his bow string and sniped a head shot.

Chloe: "If Illya was here, she wouldn't have the guts to kill a forest animal.

Shirou: "True, she's been fighting Servants in her time and monsters in Chaldea. Never once she fought something that could not fight back, her native innocent makes her who she is." Tracing a knife and stabbing the deer's arteries to let the blood flow out. "That should do it, the blood should drained out by the time we arrive back"

Chloe: "What was your Illya like?"

Shirou: "..." He pasued for a second before lifting up the deer by it legs, "I guess you're closer to the Illya I know than your sister."

Chloe: "hmmm really~?"

Shirou: "Maybe not, then again she is older than you."

Chloe: "How old was she?"

Shirou: "I can't quite remember but I think she was 17 or 18 years old."

Chloe: "Highschool age, I bet we look great (and sexy) when we're older." Daydreaming herself taller and with a bigger bust like mama.

Shirou: "Hard to break to you but, she isn't that much taller than you and Illya"

Chloe: "Eh. What do you mean by that?!" Her imagination starts to crack.

Shirou: "I guess she's a few centimeters taller than you. Also we Servants don't age."

Chloe: "I know that! I was talking about our originals, me and Illya would be in shocked that we'll be stuck short throughout middle and high school. I can't believe this."

They returned to the cabin where Irisviel was waiting for them. Kiritsugu help Shirou by making a wooden poles and stabbed it well into the ground to hang the deer. Chloe went to Illya and shared what she learned.

Illya: "EH?"

Ruby: "oh ho~" A long-lasting mahou shoujo indeed.
