Can I have a pantheon?

[Mechanical Pear]

Can a Champion of Irori, who worships Irori, also dip a level into Cleric, worshiping Shizuru? Irori is Lawful Neutral, Shizuru is Lawful Good, and the character at hand would be Lawful Good.

Yeah, there's nothing prohibiting polytheism in Pathfinder.

One of my first characters was an LE Monk who worshiped Irori and Achaekek. Really fun to blend ideals like that too.

Every single other religion based effect requires the deity in question be your "patron" (which you can only have one of) but CoI doesn't. RAW, there is nothing stopping you from having Shizuru as your patron (which is a defined term) while you still "worship" Irori (Which is not defined and is just fluff).

Pretty much all D&D derived settings (I THINK the default PF one included) have noted that most people, even clerics of other deities, worship other deities when appropriate, just that their patron gets special attention and devotion.

I really like the idea of clerics who worship sets of deities anyways-- cluster 2-5 related/similar gods together and say people who follow this "church" can take this other set of domains. . .
