There are, in fact, two other clerics of Cayden Cailean that someone managed to scrounge up somewhere.
One is missing his left arm from the elbow down and has scars down half his body and walks in an odd half-shuffling way. He's drunk all the time; his stipend pays for it, at least if he doesn't eat much, which he doesn't. Every morning, after he finishes his prayers, he walks down to the Church of Sarenrae and uses up his spells. He doesn't talk much.
The other is nowhere to be seen. According to the tavernkeep, he's working very hard on his pamphlets. Tetula hopes they'll be very informative when they come out, but doesn't want to interrupt the writing process.
She asks the tavernkeep if he's heard of any clerics of any other good gods who are in town for the convention, and receives several leads in exchange for a blessing from Cayden Cailean. She's not really sure how to do a blessing from Cayden Cailean but she kneels dramatically and very solemnly asks that this tavern be a place of friendship and merriment and good cheer, and that seems to be good enough for the tavernkeep.
