Ever since I started playing
Morrowind I'm getting a rather strong
Dune vibe from some things which I suspect might not be incidental. However when I tried to look up any info on that there seems to be very little recorded discussion on the relation between the two works.
I will not dwell much on the main plot revolving around an outsider who gets to fulfil an ancient prophecy that is popular among the semi savage but noble people that lives in very harsh conditions, as this is indeed not a concept which is unique to
Dune alone, although the similarities are rather obvious, except here we have charred ashlands instead of the unforgiving desert.
There are other details that caught my attention, for example:
The Great Houses of Morrowind seem to have more than just a superficial similarity to the Great Houses in the Dune universe. Specifically, it is easy to draw parallels between House Hlaalu and House Harkonnen on the one hand, and House Redoran and House Atreides on the other. Hlaalu are closely allied to the Empire, and so are the Harkonnens, and both these factions value wealth above honour and ancient tradition, and will not shy away from questionable means of achieving their goals. The Harkonnens mined Arrakis for immense profit and at the expense of the local population, House Hlaalu appears to have a similar mercantile interest in Vvardenfell. Both factions make extensive use of slavery.
House Redoran is the opposite of Hlaalu and preserves traditional virtues of honour and loyalty, just like the Atreides who trace their ancestry back to Ancient Greece. There is a rivalry/conflict between the two Houses. Redorant territory generally has much harsher conditions compared to the "civilised" Hlaalu. The Atreides, upon arrival on Arrakis, occupied Arrakeen as their capital and not the Harkonnen capital Carthag, which was larger and newer while Arrakeen was closer to a native settlement. Redoran architectural style may be compared to how windtraps are depicted in many Dune games. During the storms in Redoran settlements I sure get this Arrakeen vibe.
One interesting detail that I noted is that Redoran members in the game wear red and at least some Hlaalu seem to wear blue or blue-and-gold - even though the
Great Houses of Morrowind states that Hlaalu faction colour is yellow. In the original
Dune, it is mentioned that Harkonnen troops wore blue liveries, whereas the Duke Leto Atreides was called the 'Red Duke' (but green and black are also mentioned to be the Atreides colours); this was inverted in Westwood's
Dune II and subsequent games where Atreides use the "good guy" blue colour and the Harkonnens the "bad guy" red.
House Telvanni looks like it could be compared to the Tleilaxu/Bene Tleilax in the Dune universe, but since I haven't had any extensive contact with Telvanni I cannot tell for certain.
