It's one thing to boast about your powers and demand servitude. It's another thing to actually claim divinity. Nevertheless, you put your all into it. You boast of how you slew the prince of the lost Ophidians as he rose from the dead, along with his undead army, of your might in battle, your flight and fire, of your destiny to rule and how you stand to be the salvation of the kobolds of the swamp, of all peoples, if they but bow before you as their god.
Bold claim, but impressive nonetheless. A number of the kobolds seem to get behind the idea and there are even a few who go down on their knees there and then. The trio of elders, however, seem more skeptical. The one with the staff bound with tokens speaks.
"Powerful you may be, O Dragon, but we are sheltered beneath the mantle of the Bloat King and he will guard our lives and souls, not ye. For no dragon can be a powerful as the spirit of the swamps."
"This Bloat King is minuscule," you boast, "so minuscule I have never even heard of him. Who is he that falsely claims to be my superior?"
A short discussion follows, as while the elders are skeptical they are still willing to answer your questions. The good news is that the kobolds don't seem to have any objection to worshipping you; some unmentioned act in distant history managed to get the kobold race forsaken by all the gods, so no major deity will shelter them. They still have the instinct to worship, though, and need protection as well, so they tend to pray to and make offerings to local spirits or powerful entities instead. If anything, the main problem is that Igrylligus already has a patron, the Bloat King. Apparently the Bloat King is some kind of powerful land spirit who rules the supernatural elements of the swamp. In return for their worship, the Bloat King supposedly protects them from wild beasts and ensures good rice harvests. He apparently has a shrine not far from the village where offerings are made.
A) A challenger, eh? Go forth and try to hunt down the Bloat King himself and slay him to prove your superiority.
B) This creature might not even exist. Go topple the shrine; if you can reduce it to burning rubble they will be forced to question the Bloat King's worth as a protector.
C) Offer them one last chance to worship you anyway, then run amok and start burning and killing anything that doesn't prostrate itself in worship before you. If their Bloat King is real, maybe he'll intervene. If not, that's probably going to provide strong proof of either his non-existence or comparative weakness to the survivors.
