Divine magic is drawn from extraplanar sources, The user aligns their mind, body and actions with the philosophical values attributed to that plane and as the link becomes more pronounced the ammount of energy that can be drawn increases as well.
There are many different planes to draw from often called "Spheres" Each one is ruled and populated by an extraplanar entity that is created from the raw energy abundant in those planes.
The most common ways to achieve these alignments is to focus on a religious text, Saint, Holy Symbol or religious leader and follows the tenets therin, Sometimes different spheres can require opposing focus's, It is entirely up to the individual to justify and reconcile these difference sin their own mind
Each living being has a pool of divine energy it has acess to however not many ever learn to use it, Each person puts ranks in "Divine Magic" which governs how much energy they can maintain at any one time, this is equal to Skill + Wisdom, Every time a divine magic is used it drains one point from that total, some skills require additional divine energy point and most rituals will drain more than one, Skilled weilders can even gain the ability to regenerate energy in combat situations but most will have to stop for silent prayer and contemplation between conflicts.
Each sphere has a different and specific effect when the weilder focuses its raw energy and uses their will to apply it directly, The currently known spheres are as follows

Divine rituals require you to channel a mixture of divine energy and incant the ritual in a very specific fashion, If the user is unable to channel enough energy to complete the ritual they may continue to channel the energy over multiple rounds, Once the ritual is complete it must be completed immediately, The caster may not delay the ritual by channeling less energy once it has started.
It is also possible for multiple casters to combine efforts and energies to finish a ritual.
