Spirits (Small primer on ancestor physiology)
The ancestors, unlike other creatures of light, had their light located on the inside of their bodies.
ID: A diagram with an ancestor and a manta. The ancestor's light is on the inside of it's body while the manta's is on the outside.
This feature had its advantages and disadvantages. Their body served as a barrier to environmental threats, but it also served as a barrier to each other. In other words, ancestors couldn't recharge their light by being near each other the same way other light creatures can.
ID: A diagram showing what light sources ancestors could recharge from. They could recharge with nearby light creatures and light sources, but not other ancestors.
For a long time, the ancestors overcame this drawback by using portable light sources like torches and candles (hence their symbolic use as currency). The ancestors later learned how to move their light outside of their body, forming the basis of magic.
ID: Mufo stresses the importance of the candle spell.
Notes from the Mesmerized Muse:
The images above refer to the ancestors as "spirits". This is a slight mistake, as this entry mainly refers to the spirits in their living form (the ancestors).
