So I have generic fantasy Human Empire, relatively Good folks, but mostly Orderly. Racially mostly homogeneous, some elves and dwarves are present, but 99% humans. And there is the Monster Empire, which is ruled by dragons, but has all kinds of naturally Evil monsters (and by Evil I mean DnD like alignments, so tangible Evil), from goblinoids to ogres and whatnot. Pre-Threat the two sides were in equilibrium: the monsters were never united enough to pose a significant threat to the otherwise also quite powerful Human Empire (lots of magic users and a strong army + various paramilitaristic organizations), and the Monster Empire is located in a hard to pass terrain, so a formal army's movements are extremely hindered. The monsters range from threat to only unskilled or old/wounded/ill/children to the mentioned dragons, which pose a significant threat to whole groups, though not unbeatable by any means. Border skirmishes were regular before the alliance.

They both got undeniable proof that there is some Generic Threat that threatens the very existence of the world, and the lead dragon bands together with the Human King to stand togetherish against the threat.

The world is a band of land from west to east, bound by mountains and waters. Monster Empire is to the west, Human Empire is in the middle, and the Threat comes from the east.

The thing is, the threat is yet to materialize. What are some key points I would have to keep in mind when thinking about this? I would imagine the dragon would keep a sizable force in Human Empire, because of logistics, if the threat arrives (and they have no clear idea of how long it will take from the first actual sign to the invasion), they have to be there. So right now, there is a whole family of dragons (Evil, macho, aggressive), a good number of giant sized creatures (ogres, trolls, actual giants) and a sizable array of smaller goblionoids, orcs, kobolds and other cannon fodder.

Is there any kind of historical reference for this? That might be a good basis for it, sans the Evil monsters part.

  • $\begingroup$ Welcome to Worldbuilding. Are you asking for historical reference of dragons and goblins fighting on the same side of humans? $\endgroup$ – L.Dutch Oct 2 '18 at 13:04

    $\begingroup$ Since the Monster Empire is Evil and behind the Humans, it's very possible that they'd let the humans bleed the Threat down to a manageable size while the Threat wipes out the Human Empire. This would allow the Monsters to defeat the Threat and then take land where the Humans lived. $\endgroup$ – RonJohn Oct 2 '18 at 13:10
  • $\begingroup$ @RonJohn well they already formed a pact because they considered the Threat big enough that separately they both'll die. It's a different matter that it might be a ruse from the Dragon because it needs access to some resource, but on the surface they are both cooperative, so the Dragon has to keep up appearances at least. There is a lot of mistrust going around. $\endgroup$ – Martin S. Oct 2 '18 at 13:34
  • $\begingroup$ @L.Dutch if you phrase it that way, it sounds silly for sure. I meant more like a situation where two, supposedly hostile powers are working together, plus dragons. $\endgroup$ – Martin S. Oct 2 '18 at 13:35

    $\begingroup$ An historical reference for enemies working together against a common threat ? You could practically pick a random war in history and find stuff going on like this behind the scenes. Way too broad. $\endgroup$ – StephenG Oct 2 '18 at 14:03

The US and Britain worked with the USSR in WW2.

It's not exactly like your scenario, though, since the US+Britain and USSR made Germany fight a three-front war whereas your scenario is a one-front war.

More importantly, there were people in US+Britain who were deluded into thinking that the USSR was a Workers Paradise.

  • $\begingroup$ Hmm, I wonder, were there instances when there was peace and the two sides were in the same position? Probably not before the end of the war, but after, before the Cold War started to form with the USSR becoming openly hostile. Should I look up post war, pre divide Berlin (not an easy Google I assure you)? $\endgroup$ – Martin S. Oct 2 '18 at 13:37
  • $\begingroup$ Three way alliance did not make Germany do anything except, ultimately, lose. Germany chose the 3 front war. USSR had a pact with Germany and was very happy to sit on the sidelines and watch Germany and western powers slug it out. Google Operation Barbarosa - for reasons historians still debate, the Germans attacked the USSR before Germany had finished with Europe. One can make a strong case that in doing so they bit off more than they could chew. $\endgroup$ – Willk Oct 2 '18 at 13:42
  • $\begingroup$ @Willk the Germans never left Europe when invading the USSR. $\endgroup$ – RonJohn Oct 2 '18 at 13:46
  • $\begingroup$ @AlexP - a little help here? $\endgroup$ – Willk Oct 2 '18 at 14:09
  • $\begingroup$ @Willk help with what? The Asian-European border is at the Ural mountains and Caspian Sea. Germany never got that far. (It's true that they bit off more than they could chew, but that's irrelevant to the Answer.) $\endgroup$ – RonJohn Oct 2 '18 at 14:17

Continued from my comment...

There's a TV show running just now, "Britannia", that tells a story (a story expanded and exaggerated for the sake of romance/theatrics) of the second attempt of the Roman empire to invade Britain.

As the story is told (minor spoiler), after the Romans establish a foothold, while considered to be demonic outsiders by one dominant tribe, they're still possible allies in an upcoming war against the other dominant tribe. Both tribes are willing to "sleep with the devil" against the more hated devil they know.

This kind of thing happened and was encouraged by the Roman Empire as it made its conquests, many times.
