Shayda is the architect of the Shayzien House in Great Kourend. She is located in the tent directly north-west of the Shayzien Bank. If you have 100% favour and have locked it in, she will be next to the statue of the castle in the middle of Great Kourend instead.
Players must speak to her after gaining 100% favour in the Shayzien House as part of the Architectural Allianceminiquest. She builds the armour and weapon of the statue.
