Crag linnorm

 Yesterday, we covered copper dragons, and as much as i hate to say it - good old mettalics and chromatics are beginning to feel a bit... mundane. If you want dragons that feel primal, destructive, alien, linnorms are where its at. Of them, the crag variety, while being the weakest one we got as of bestiary 2, might get some recognition - from its appearance in owlcat's pathfinder kingmaker video game.
Also, do note that while a crag linnorm speaks three languages, it has basically animal level intelligence.

Traditionally, when a chieftain of one of the Eleven Tribes of Evershore needs council, a shaman is sent to the Elvenspire. The ancient monolith is said to hold the collective knowledge of ancestors hidden within it, which the shamans access by falling asleep at its base, and having dream-visions. Several days ago, however, a monstrous, serpentine beast arrived from beyond the sea, coiled around the monolith and fell asleep. While its usually docile, whenever a shaman tries approaching it it flies into a violent rage, and three of the eleven sages already lay dead. As Times Of Trouble come ever closer, the shamans knowledge is needed more than ever, and unless a different source of power is found or the beast slain, the tribes are sure to perish.

After eating Gustaff Ustaff, the King of Narfleek, an ancient and vicious linnorm named Nagaytasha crowned herself the new queen. The ceremony itself was a perverse mockery of the land's tradition - yet noone dared raise their hand against the queen, as Narfleek was always ruled by fire and blood. However, word has come of the Sovereign, a mighty blue dragon monarch, offering her his hand in marriage. A draconic marriage, of course, is unheard of - but the Sovereign plays by the letter of the law, even as he mocks its spirit and intent. If the marriage comes into fruition, the Sovereign and his legion of blue-scaled Dragonborn grunts would gain a foothold on the last free continent, and would surely use it to stage a final invasion. A group of spies recruited from the ranks of the Last Alliance is tasked with using any means necessary to thwart the marriage.

Flametooth is the ancient, serpentine guardian of Hapthus's temple. Flametooth is also dying, after having guarded the temple for exactly a millennium. A temple guard and his young apprentices are tasked with finding a fresh crag linnorm egg to replace flametooth, and bringing it before the old beast succumbs to age - keeping up the charade that the temple's draconic guardian is truly immortal.
