The Icosantheon is a host of twenty deities bound not by a common origin, but by a united conservatorship of the immaterium that forms the sides and edges of the material plane.

5. Eirsival

Eirsival is known as the Knight of the Final Thunder and the Coming Storm. She is the last of the Storm Mothers, agents of the primal divinities from before the fall of the Chthonic Gods. The Storm Mothers oversaw the destiny of those who would die defending others. In a twist of what could be considered irony, they were unable to foresee their own destiny, dying to defend the birth of mortals during the Gogolmachy when gods and elder beings first came into direct conflict and destroyed so much of reality, including entire alternate histories and places where technology was far more advanced than the current world.

Along with the other Storm Mothers and the First Heroes they had guided, Eirsival stood to hold the Final Line against aberrant horrors that sought to unmake the rules of the material plane. Had they failed, there would be no natural order to things, just a whirling tumult where the will and power of an entity were the only limits of what it could force others, and matter itself, to become. Though the Final Line did not break, when the maelstrom fell back, only Eirsival and Ixalicor, the progenitor of all unicorns, remained. Ixalicor swore to serve as Eirsival’s mount for all time, and Eirsival swore that those who defended the innocent, weak, and abused should never have to do so alone.

And in that moment, she went from the last of a line of angelic servants to being a deity.

Eirsival neither requires nor even requests worship, as she wishes to support all righteous defenders, whether they pay her obeisance or not. However, that very fact draws some to venerate her and wish to spread her name, and as long as they do so in the name of protecting a better world and respect the lives in the current world, she does not refuse them. Her temples are few, but tend toward massive fortifications that can take in and defend vast populations when needed. Slightly more common are stables and cavalry forts with a small shrine to her, as the friendship between her and Ixalicor has carried down to many forms of equine.

Eirsival believes that rules and order are a necessary part of protecting the rights and dignity of all things, but she also accepts that rules and order can be used for darker purposes. Thus while she has a natural distrust of anarchy and randomness, she does not inherently oppose it until it begins to impinge on her quest to protect all. Eirsival is a close ally with Karrackar, and where she and the Shade Dragon disagree on some finer details of how to best proceed, their mutual respect is so great they simply defer to one another within their specific areas of concern. Eirsival actively dislikes Garuuhl, and considers him excellent proof that if the ends is used to justify the means, evil will eventually result. She largely ignores other members of the Icosantheon, and other gods in general, unless their interests and goals somehow overlap or oppose her own.

*Eirsival is Lawful Good, and accepts worships of all good alignments, and those who are Lawful Neutral. She supports all efforts to protect and aid others, and acknowledges that there are often many ways to do so, but does not tolerate evil in any form, or anarchy for the sake of anarchy.
*Eirsival’s colors are sky blue, silver, and pearly white, often in wind and cloud motifs. However, her colors are for times when color is appropriate, her worshippers feel no pressure to embrace those colors unless they both desire to and are safely can.
*Her favorite weapons are any form of lance or spear, most often one sheathed in lightning.
*Her favored animal is the horse and all horselike creatures, especially pegasi, unicorns, and hippogriffs.
*Her servitors are winged unicorns the color of thunder and lightning, tengu spearmasters who are wandering teachers, and smiths, especially lance-smiths.
*Her holy symbol is a single bolt of lignting, surrounded by darkness.
*Her areas of concern are destiny, dignity, heroes, honor, loss, resolution, and solitude.

Pathfinder 1st Edition Rules:
*Her domains are Air (cloud, lightning, wind), Glory (chivalry, heroism, and honor), Good (friendship), Law (loyalty), Protection (defense, fortification, and solitude), and Weather (storms).
