The background story of Defenders of Oasis
is based on ancient Iranian mythology. Unfortunately, some names are not spelled very precisely and suggest a slightly wrong pronunciation, for example Zahhark
instead of Zahak
instead of Jamshid
. You can read about Ahriman, his servant, the dragon Zahak, the legendary king Jamshid and his descendant, the brave Faridun, in the famous epic poem Shahnameh
by the great Iranian poet Ferdowsi.
