When I populate a castle, dungeon, landscape etc - I want it all to make sense. For some monsters (like the Orc) the Monster Manual says what other monsters you would expect to find nearby - but is there a resource with this kind of information for other creatures?

For instance, I have a small dungeon with some Dark Elves... but having 3 or 4 rooms with yet more elves would get boring. I could add a pen with some wolves... but that's an easy example. Is there a nice tool which says "oh, you have Goblins.. they will play well with..... {whatever}.

I could just throw in a load of creatures, but common sense says that a dungeon full of different beasts would soon end up fighting before the PCs got there, and all the characters would find is a pile of monster corpses.

Is there any existing resource which will tell me what creatures are often found together in dungeons?

    \$\begingroup\$ I don't think this can be meaningfully answered - depending on your world, goblins might be slaves of drow, or they might be the drow's most bitter enemy. Even within a world, it's pretty easy to come up with an explanation for almost any combination of monsters. \$\endgroup\$ – Miniman Mar 17 '15 at 13:17

    \$\begingroup\$ It could also depend on whether you're working with a published world or not and which version of DnD you are using \$\endgroup\$ – Wibbs Mar 17 '15 at 13:19

    \$\begingroup\$ When I say Compatibility, I mean put them in two rooms connected by a corridor, and they wont automatically kill each other above anything else (without having to put locked doors in the way) \$\endgroup\$ – Jaffa Mar 17 '15 at 13:28

    \$\begingroup\$ If I understand correctly, you are effectively looking for some sort of "friend/neutral/hostile" list that lists every combination of monster A vs monster B? \$\endgroup\$ – Theik Mar 17 '15 at 14:03

    \$\begingroup\$ I don't think this question should be on hold. I understand it well enough. Globlinoids would all hang together, similarly with dragonoids. The current Tyranny of Dragons demonstrates that dragonoids work together sometimes. In the underdark I can think of a few, though don't have the MM on me nor have it memorized even a little, but the elves themselves obviously, dueger, some sort of cave gnomes (if they still are around in 5e), Spiders of course, various underground "creatures". Maybe a beholder or two past the edges of elven territory. The underdark is just like the overworld in that way. \$\endgroup\$ – Escoce Mar 17 '15 at 14:56
