Walid is a minor character in Horizon Zero Dawn. He is a Carja guard stationed at Daytower.
History
After being sent on a patrol into the Valleymeet east of Daytower by Captain Balahn to investigate rumors of corrupted machines, Walid's party was attacked by Corrupted Watchers outside the Forsaken Village. Heeding the words of Lakhir who stressed the importance of reporting back to their captain, Walid managed to retreat back to Daytower and report of what happened to Captain Balahn, being the only known survivor at the time.
Horizon Zero Dawn
As Aloy passed through Daytower on her way to Meridian, Captain Balahn asked her to search for more survivors as sending more Carja to investigate could impact relations with the Nora, having Walid explain to her what happened.
