Sage Freke is a character in Demons Souls.
Sage Freke is initially found in a cell in the Tower of Latria (3-1). The key to his cell is found late in the level, so some back-tracking is required. After his rescue, Sage Freke may be found in the Nexus, next to his apprentice.
He teaches advanced magic by using Demon’s Souls. See the Magic/Miracles section for a list.
