Winged creature very lost in Western Norway (6)

I believe the answer is:
wyvern
'winged creature' is the definition.
The definition suggests a singular noun which matches the answer.
'very lost in western norway' is the wordplay.
'lost' is an anagram indicator.
'in' indicates putting letters inside.
'western' becomes 'w'.
'norway' becomes 'n'.
'very' is an anagram of 'yver'.
'w'+'n'='wn'
'yver' inserted within 'wn' is 'WYVERN'.
Can you help me to learn more?
(Other definitions for wyvern that I've seen before include "1950s Vauxhall model" , "Heraldic device" , "Heraldic beast" , "In heraldry, a dragon with wings, two legs and a barbed tail" , "Heraldic winged monster" .)
