Wild moors, right on the map, dark and gloomy (6)
I believe the answer is:
morose
'gloomy' is the definition.
(I've seen this before)
'wild moors right on the map dark' is the wordplay.
'wild' indicates an anagram.
'right on the map dark' becomes 'e' (I am not sure about this - if you are sure you should believe this answer much more).
'moors' with letters rearranged gives 'moros'.
'moros'+'e'='MOROSE'
'and' is the link.
Can you help me to learn more?
(Other definitions for morose that I've seen before include "Sullen. bad-tempered" , "Down in the dumps" , "dark" , "Silent, gloomy and ill-tempered" , "Gloomy and unsociable" .)
