Fáfnir’s Storeroom #1
Take the first elevator up from the beach and then turn around to face it. The Raven is perched on top of the elevator.
Fáfnir’s Storeroom #2
Once you find Sindri’s Shop, look up and to the left a little to see this pesky Raven flying overhead.
Fáfnir’s Storeroom #3
Continue down the path from Sindri’s Shop and then check the branch sitting in front of the waterfall to spot this Raven.
Fáfnir’s Storeroom #4
Once you’ve defeated the large group of Draugrs in the clearing you will see two entrances, one beneath the waterfall and one to the left of it. Look on top of the one to the left to spot this Raven.
Fáfnir’s Storeroom #5
When you reach the pedestal room past the waterfall, look into the air to find the last Raven for this area.
