Chosen
Within Helia, deities can exert their will within areas of their direct domain and influence. There are restrictions and limits to the extent at which their power can be wielded, however. Direct action by gods outside of their home plane requires an immense amount of magic and energy. There must be incitement from other mortals via prayer, ritual, and even summoning to lighten the burden. On the other hand, deities can interfere with mortals if their own domain or vitality is being threatened.
All this is not to say that deities must simply observe and obey the will of their followers. Like mortals, gods have ambitions and desires, but must go about achieving these goals through other means. One of most prominent means is by selecting "chosen." Chosen are mortals who have been handpicked by a deity to carry out their will. They are given direct power from their patron and retain their agency.
