Speaking of his beard, it's a completely new creation that you won't find anywhere else, as it was made specifically with this sim in mind. So that content had to be made, and since I'm hardly the master of CC creation I had some wonderful and talented simmers come to my aid - most notably Meduza (who agreed to convert Ragnar's hair from Sims 4 to Sims 2) and Io (who provided me with the idea and resources to make Ragnar's beard a reality). Simmifying Ragnar turned out to be a way bigger project than I had initially thought, for two reasons: for one, making sims after real people is always a challenge in its own right, and doubly so if you're not familiar with the person you're making and for another, Ragnar dons a quite unique look in the show that was very hard to translate into sims due to lack of proper content.
Did someone mention 'exclusive custom content'? Why yes, yes I did.
