Siyus is the deity of knowledge, alchemy, and scholars. One of her main duties is to oversee the training program for new halfling combatants alongside Ioh and Iot, although she gets the final word in all matters regarding their practises. She is formal during all occasions but speaks rather bluntly. Her emotions embarrass her and she works hard to hold back any excitement or happiness she feels. She excels at forgery and handwriting. Her closest friends are Esm and Loms.
Siyus' symbols are purpurite, the mole, and the quill. Her armament of choice is the grimoire.
