Candle light wards might also be another thing. I can see Tsava Leko having wards based on candles around their caravan. Though I think his own wards where originally dolls that he used to focus elemental powers into.
Witchy tip. I have an obsidian scrying mirror which is useful to amplify spell rituals. Place the appropriate crystals on the mirror and make sure you can see the flame of your candle in its reflection.
