This is the face of good in the Fiend Folio. Your best chance at a friend or ally. The enemy of evil. The protector of order and weal. The flumph.
What sort of cosmology gives us the flumph as the friend of the paladin? I mean, the Monster Manual has some odd options for good creatures. No angels, but we get shedu, lamassu, ki-rin and couatls. But the flumph takes the cake.
So imagining the world that allows for flumphs as a great force of good really implies a good that is alien, weak, and set upon by external forces. A good largely unable to keep evil at bay, and which needs to survive by avoidance, escape, and surprise. And a force of good that can't even really speak to you. Which really leaves the good guys in the lurch.
