Malchin is obviously a historical person in The Stormlight Archive. He is mentioned only in the Epigraph for Words of Radiance: Chapter 57.

Malchin was stymied, for though he was inferior to none in the arts of war, he was not suitable for the Lightweavers; he wished for his oaths to be elementary and straightforward, and yet their spren were liberal, as to our comprehension, in definitions pertaining to this matter; the process included speaking truths as an approach to a threshold of self-awareness that Malchin could never attain.
