This website is to help detail and explain some of the different worlds created by author Brandon Sanderson. The cognitive realm aka Shadesmar connects the spiritual and physical realms to each other within Sanderson's Cosmere. This realm may also be used to travel to different worlds via the 'perpendicularities' which are sort of portals that exist due to a large amount of 'investiture' or power that stems from the Gods (Shards) of the Cosmere. If you'd like more info check out Sanderson's website here.
