I often wonder just how radical tribal loyalty is in Phyrria. Especially during the War of Sandwing Succession.
Webs threw himself on the mercy of a Queen he betrayed that was infamous for executing those that failed her on the chance that he'd be let back into his tribe.
The Scorpion Den received the same importance on the map as a royal palace purely by the strangeness of being a place multiple tribes co-existed.
No matter how much Deathbringer disagreed with his orders when faced with the threat of exile were he to disobey the assassin kept his mouth (mostly) shut and got to work.
Nearly every dragon the Dragonets of Destiny came across mentioned how weird the they are in their affection for one another as though inter-tribal bonds were a truly alien idea.
Maybe the real reason Dune didn't tell Sunny the cure for Sandwing venom and Webs didn't teach Tsunami Aquatic was because even though the guardians had forsaken their tribes to work for the Talons of Peace they still couldn't bear the thought of potentially leaking a tribal secret.
Maybe the reason not a single dragon even suspected that Sunny might be a hybrid in spite of how obviously different she looked was because hybrids truly are that rare in a continent dominated by tribal fanaticism.
