[The common area is a bit in disarray, currently. One of the couches has been pushed askew, opening up more floor space, and a young man in leather armor is sitting on the floor with his phone, tapping out a reply with fingers unused to typing still.

And there's a dragon slightly larger than a clydesdale that seems to be responsible for the disarray, judging from how he's sticking his head under the area rug curiously. When Loki magics himself into the room, Toothless sits up quickly, rug draped over his head, peering at him with huge green eyes. Hiccup startles to his feet (foot) too, dropping the phone.]

Oh! Hi! Are you- Uh, 'trickster'? That was fast, wow.

One of these days I'll get used to magic, haha. [He's met the other Loki. They shared a flight far above the city. He doesn't make the connection, though; they don't look all that much alike, and their demeanors are certainly different. Hiccup relaxes a little when he realizes that this is the person he was talking to, and smiles wide, posture easy, waving a hand at the night-black reptile.

Toothless tilts his head to the side curiously, trilling out an inquisitive noise before he drops to his belly again and starts pulling the rug off his head with his front claws. His tail swishes, the mismatched fins knocking something decorative off the wall.]

Ever graceful and magnificent. [He remarks dryly.] Yeah, this is Toothless. I'm Hiccup.

The second time I got close to him, he didn't seem to have any teeth. Night Furies' teeth retract. [He laughs a little, fondly, watching his dragon. Toothless spots the ball of light and his ear fins perk up, his body slipping into a cat-like crouch, tail swishing back and forth. Then he pounces, mouth partly open and gummy.]

No, we don't have real magic at all, just in stories. It's been interesting, being here and seeing all this new stuff and new people, hearing about new worlds.

Right! [Hiccup goes to dig in a leather bag for a worn, old-looking book. It's hand-bound in leather and the pages are made of thick yellowish paper, definitely materials from long before modern paper refinement and machine binding.] It's not all my notes, my friend back on Berk has a lot of our research too, but it still might be interesting. [He removes the folded, pasted-together mess of his archipelago map and lays that on the table for safekeeping before he hands over the journal.

The pages are filled with charcoal sketches of different species of dragons, labeled diagrams, quick facts in Norse runes. The first pages are all about Toothless.] You don't have dragons in Asgard?

Oh. [He seems a little sobered at that. He knows, intellectually, that worlds are different, and Asgard is probably very different, and who knows what creatures lurk in the other realms, but the thought of hunting anything down puts a slight furrow in his brow. It wasn't all that long ago that vikings hunted dragons, made trophies out of their heads and bones and skins. Talking about dragon biology, that's much easier.]

No, not usually. Maybe some species... We have tried to puzzle out how a Gronckle is able to fly, they're really heavy. Night Furies probably have the biggest wingspans, though I think Timberjacks come close, proportionally speaking of course.

I know with Night Furies, the fins are important for flight. [He points to one of his early sketches of Toothless from above, the smudged out left tail-fin.] Toothless was injured here. He couldn't get any altitude or steer himself until I built him a new one. It's different for every species, though, since they don't all have the same physical structure.
