Okay, so this might be better off in the character devlopment thread (not sure) ... I am working on a story that isn't set on Earth but that has quite a few Earth(ish) qualities. Everyday animals that we might see (horses, dogs, birds) etc. are present. Think Terry Pratchet and Discworld for an equivalent. My question is, as I introduce the mythical creatures, is it better to stick with the standards (ogres, dragons, sprites, etc.) or to introduce new beasts - maybe based on these? The terrain descriptions would be very earthlike - no neon clouds or inverted waterfalls or anything. Should I stay with what is recognizable?
