Golo: as has been said, hard information about Belisarda is in short supply, but here's what I know/believe:
-Belisarda is the incarnated life force of the world.* Several of her priesthood's spell corroborate this by failing to function if the caster isn't on Arcanis and by directly appealing to Her to manipulate a quality of the planet.
-Belisarda's dedicated priesthood are the Ardahiri -the Lifewardens. They were formerly Ardakene only, though that tradition gradually changed. The Ardahiri have a surprisingly good track record for the promotion of tolerance and diplomacy, and are almost always the voice of patience and reason.
-Prior to being imprisoned by S'koreth the great Sstheric Wizard Belisarda was apparently wandering mad and grief-stricken for the loss of someone -I know of no clues as yet as to who or what. When she was located she was rapidly and randomly polymorphing through the forms of elements (but not Elementals) such as pools of magma, trees, a small lake complete with fish, birds, and wailing in great distress.
-Belisarda's capture was a major Charlie-Foxtrot. Once engaged she tore through a legendary lineup of heroes like they were toilet wet paper, variously pulping, incinerating and exploding them. S'koreth himself nearly perished when she began ripping the oxygen right out of his lungs.
Besides making me chuckle the point of this example is that She has/had very direct, powerful connections to the usual four Elemental sources.
-The Elorii might not be the only known faith of Belisarda. A Gar (formerly Goblins) tribe was found far and deep in the Corlathian mountains who worshipped a powerful Life God and who pre-dated the arrival of the PoM. It's also possible She's popular on other hemispheres of planet; for all the carnage and drama we're only adventuring on one
continent. If we had one-hundred-
million-dollars laying around we'd have a terrific MMO setting waiting to happen.
-Belisarda has no Valinor. Duh, right? But also no other equivalents. So if witness some kind of act or manifestation at one of Her holy places there might be a hidden priest around...or you're seeing a personal divine act.
Place nice in Mom's house.
-Belisarda is one of only three deities credited with an action of raw Creation. Herself, Kassegore, and Yig. Notably the Pantheon of Man doesn't take credit for
the creation of humans, and humans were (though I could be mixing up the dates) once encountered by the ancient Sstherics during the nadir of their empire.
-There was a document in the last campaign (I want to say errata to the original Codex Arcanis) that cited Belisarda as having the alignment Neutral Good. This caused quite the stir at the time, but was eventually disavowed and forgotten.
-Lastly, the Skinless Schism. The Volurii, the Malfean Elorii of the Fellglade who elected to remain on the borders of the great southern swamp and wage an eternal war on the remains of the Sstheric empire, were met one day by a powerful spirit that claimed to be Belisarda. She said she'd escaped death at the hands of the PoM, but had been
skinned alive while making her way^ back to her children. She said she'd gone to the other two nations first, but that they'd rejected her with repulsion and disgust. She won the trust of the Volurii (how is a
serious question without an answer) and entreated them to start
bringing her skin so she could be healed and walk among them, Her True Children, again.
They complied enthusiastically, and during the Second Battle of Semar she nearly manifested physically when the Malfean forces seized control of a mass sacrificial ritual a Sstheric army was using to call Haullis the Varn God of Slaughter into Arcanis.
Yeah, a true "bring me my brown pants!" Arcanis moment.
Gratefully, both armies failed.
The current state of politics between Malfea and the other Eloran nations remains unknown. They were previously distantly allied, though the Malfeans would show no mercy to other Elorii who they believed were associating at all with Humans.
*Yes, this
does raise interesting questions about divine boundaries. Where does Yarris start and Belisarda end? Or Saluwe`? If Belisarda can cause natural disasters, can the Gods of the Pantheon intervene?
I once asked Henry what the Sun was called before the PoM arrived. He replied, "the Sun." I feel as though my questions is unanswered, but it does raise another interesting question: how much of a divine presence is invasive? Is Illir a shroud that interposes himself between the natural Sun of Arcanis's known solar system, or do they harmonize together into once concept? If there were Sun worshippers did Illir get them automatically when He happened?
^This memory is rather imperfect as to whether she was skinned by the PoM, or by Infernals/Other Things in the spaces inbetween.
