Homecoming
So it's really interesting that Taliyah uses a Yasuo quote at the end; not only does this show her training and fondness of him, but this may indicate she has a fatalistic view of the confrontation looming with Azir. She is clearly a powerful mage given the amount of earth she moves with clear ease.
Also it definitely look Azir is the bad guy, but I'm not sure if I like that or that he is really a bad guy.
Overall, hype intensifies.
Edit: Maybe Azir is being scapegoated by a conspiracy that Xerath has actually set into motion. Azir is thought to be the threat to Shurima when in fact Xerath is the real threat all along. Just a possibility.
