He lands on a planet that's all ice and has three suns, which is very pretty. Uninhabited, though, so it's not his next destination—his aura is still flaring. He follows it, crossing interplanetary distances in the blink of an eye, finds the next door's location in the middle of nowhere, and floats/walks through it.
"You took a dragon down on your own? Shit. Guess that explains why no one filled you in. ...You should talk to Eleanora. She's the director of Azimuth - that's the big flying city I'm from. If you can fight a dragon alone and come out alive she'll want to get you deployed. Uh, assuming you want to work with us, I guess."
"I mean, if this were an actual war I'd want to hear both sides but if it's literally a bunch of nonsapient dragons who may or may not be commanded by someone but if so it's someone who hasn't actually explained why or anything like that, then yeah I want to work with you. But I'd like to eliminate the problem altogether and I probably have the means to help you do so."
"If you're bringing even more to the table than being a whatever-you-are that can kill a dragon in single combat you should definitely talk to Eleanora. Do you have a place to stay already? If not, how do you feel about living on Azimuth for the time being?"
"I don't have a place to stay, and I don't strictly need one, I don't sleep or eat or need to breathe, but it's sounding like a good idea to do that, yes."
"Sounds good to me, let's get going," Tobin says. "...shit, how're you gonna get in? Uh, Azimuth's not designed to be easily enterable, 'cuz anytime we need to get back into it we can just shoot ourselves in the head. Uh, I guess you could stow away on a shipment of supplies, if I told 'em to they'd probably let you, Sky Knights can pretty much get away with whatever. We'd have to go to whichever the hell city has a Gate up to Azimuth, though, which means you'd have to navigate the Gates between inner cities, which is a fuckin nightmare. ...Fuck, did I explain Gates? They're big stone portals you walk through to go from city to city, they come in pairs. But there's no big hubs like there used to be before the dragons showed up, there's like... loops? This city's connected to that one's connected to that one's connected back to the first, and if you wanna get to a city that's not in that loop you have to travel overland, and none of the Gates lead to a city next door, they all lead somewhere random halfway across the Polity, it's bullshit."
"Or I could bridal carry you through the air and, like, knock on a window, if you're up for that."
And they fly: up through the skylight, and then up through open air for a while.
Azimuth comes into view after a time. It looks like someone tore a piece of the ground out of the ground and fixed it in the air, then built a military base on top of it out of trees and hung a bunch of organ pipes off the bottom.
"Hmm... could take you up through a drop shaft, dunno if I could pry one open with my feet or not... all the skylight are grated... fuck, this is tricky. Um, tell you what, we'll land on the lip of the island, then how do you feel about riding on my back? If you fall I am 100% capable of shooting down faster than gravity and catching you."
"If I fall the ground will be the worse for it, don't worry. Is there a use for riding on your back that's not merely being accompanied by you so I am allowed in?"
"My hands'll be free so I can fly up a drop shaft and pry open the door, 's'probably the only way in."
"Ah, riding on your back to the top of the shaft, I misunderstood. Yes, that's fine."
Fly.
The drop shaft is lit from within with periodic globs of luminescent fungus. The trip upward is extremely boring.
Eventually they reach the top. The door is circular, divided in half. Tobin reaches up and wiggles his fingers into the seam, then pulls.
He growls at the doors while he's doing so: "fuckin - I'm not a lindworm you dumb shit - take the goddamn hint - let me in you useless vegetable - "
Eventually the gap is wide enough for both of them to fit through. Once they're inside, the doors snap shut. He lands, lets Sadde climb off.
This room is also circular, made of some gray wood that looks and feels almost metallic. It's lit by glowing blue-white mushrooms hanging from the ceiling.
"Okay," Tobin said. "I don't know about you but that felt extremely stupid to me. Let's go, I'll show you to Eleanora's office."
"I'm not sure you should blame your architects for not anticipating the possibility of extradimensional help who can't shoot themselves in the head to get here. But do lead the way."
"You're not a big jokes guy, huh." Way: is led.
It winds, up staircases and down corridors and through the curtains-plus-squiggly-little-passageways that this world likes to use instead of solid doors.
And then Tobin leads Sadde through the widest curtain and squiggliest passageway he's seen so far, to a wide semicircular office...
...with a desk in the middle and a woman behind it.
"Hello, Tobin," the woman says. Presumably this is Eleanora. "Who is your companion?"
"My name is Sadde. I'm from another universe. I killed a dragon in single combat and was unhurt. I have other forms of useful shareable magic."
She leans forward and steeples her fingers. "Really. I'm very pleased to meet you, Sadde. Do you prefer Tobin to stay here while we talk or are you comfortable speaking with me alone?"
"I used to be human, but then I became what I currently am. My species—vampire—is ageless, does not need to breathe, sleep, blink, rest, or actually move at all; we do not get sick, we are extremely durable and if you remove a limb we can reattach it—and that's in addition to personal, unshareable magic I have which allows me to manipulate my own biology pretty much without constraints including doing things like regrowing limbs or turning them into spikes which I can drive into a dragon's skull, or generating pretty much any biological matter I want. We are very fast and strong, have much better senses than humans, have perfect recall of everything that has ever happened after we turned into a vampire, have ridiculously accelerated cognition and much more room in our brains. We also become much prettier after we turn. The only way to kill us is breaking us into pieces and setting us on fire.
"Now for the drawbacks. To turn a human they must be injected with venom, which is produced in greatest quantities in our mouths, and then over the next three days the human will suffer agonising crescent pain beyond anything you could possibly imagine or actually endure. It is very common to beg for death. There is absolutely no way I can overstate how horrible it is, and absolutely nothing I can tell anything or anyone that will actually prepare them for how bad it is. Newborn vampires are often so overwhelmed by their new senses that they have a lot of trouble resisting their every impulse, including murderous ones, but this is helped by advance knowledge of it. Newborns are also much physically better—stronger and faster—than regular vampires for about a year after turning. The perfect post-turning memory also drowns out most pre-turning events if the vampire doesn't particularly focus on them soon enough.
"We subsist on mammal blood—but nonhuman blood tastes worse than the worst rotten piece of food anyone's ever eaten, while human blood tastes and smells so good most vampires in my world used to be unrepentant serial killers because of it before the current government took over and outlawed murder. Because of this, it is extremely difficult to turn a human by biting them without actually eating them. Furthermore, drinking human blood makes a vampire less likely to be able or willing to resist it in the future, as well as more feral and antisocial and less capable of living in large groups. There is a set of instincts that completely replaces human ones which also automatically treats other vampires as threats and humans as food. There are associated physical changes beyond becoming prettier; a regular vampire's skin sparkles in the sun, our eyes turn red when we've recently fed on a human, gold when we've recently fed on an animal, and black when we're hungry, and our teeth are much sharper even in comparison with our hardened skin. And a vampire is always at least a little bit hungry, which is reflected in a burning sensation in our throat that echoes the pain of turning and only gets worse the longer it's been since we've last fed.
"When a vampire lays eyes on a person they would be mutually romantically compatible with, they are immediately and eternally in magical monogamous love with them; if the target is also or becomes a vampire, this becomes reciprocal. In case a vampire looks at multiple people they'd be compatible with at the same time, they get this mate bond with all of them. Female vampires cannot conceive, but male vampires can impregnate human females with hybrids, who take one month from conception to birth in a process that often kills the mother if special precautions aren't taken to immediately turn her.
"Any questions so far?"
