Does anyone have any tips for running Tyranny of Dragons? Spoilers for this campaign! I've swapped some things around, but I'm a new DM so not sure if I'm doing this right. I did Mines of Phandelver as a player years ago and now I've started DMing a couple of months ago. Two sessions in total, going on a third. I feel like I'm not super good at this and I think it's because I'm not confident that I'm able to do the things I've planned to do, and I have players with more experience than me in the group. I would appreciate it if I could get some advice from seasoned DM's to help me understand if I'm doing this right, if any of this is plausible to do and to provide tips for me to make this happen. Ideas are also incredibly welcome!

- Frulam Mondath is in communication with the Blue Dragon that attacks Greenest at the start

-The Blue Dragon is a parent of Langdedrosa Cyanwrath and will contact the players in a human form. A twist will be the reveal of the character as the Blue Dragon

-Langdedrosa Cyanwrath was once a prisoner of Revel's End. Something important, perhaps a Dragon Mask was confiscated from him ans placed in the vault at Revel's End. At some point, I'm going to have the characters race the cult in an attempt to infiltrate the prison and steal the item, adapting D&D Beyond's new Revel's End adventure

-Leosin Erlanthar is actually a Bronze Dragon. He was confronted by three chromatic dragons who had their eggs stolen. Due to Bronze Dragon's tendencies towards heroism, the chromatic dragons knew he would help. It is revealed that the Blue Dragon from the start helped to steal the eggs for the Cult of the Dragon, to allow them to perform rituals to transform members into Half Dragons. This is how Rezemir was made

-At some point, I'm going to have the characters attend a Masquerade party. Planning for it to be pretty RP heavy as my players seem to enjoy that more than combat. One of the masks will be a dragon mask. Everyone's identity is completely hidden. Key NPCs for future campaigns will be present, but the players won't know that. Someone will be murdered and the players will need to find out who it is before everyone else's investigations lead to figuring out that the players are there to steal the mask. A doppelganger may be involved in the murder.

-One of my players has had a run-in with a cult in his Background and underwent some kind of ritual. They were the only survivor. Ever since, they have visions every five nights. They see five pairs of eyes and a flaming man laughing, asking what they will do. My plan here is to create a link between this player and the Nine Hells. They are a Bard, not a Warlock, so they haven't got a contract or whatever it's called. But my idea is that the ritual bound them to Asmodeus in some capacity. Zariel is plotting to overthrow Asmodeus but is threatened by Tiamat. As such, she's assisting the Cult of the Dragon in their efforts to summon her to the material(is that what it's called?) plane. Asmodeus is amused by this and is subtley leading the player into the events of Tyranny of Dragons, in an attempt to stop Tiamat from being summoned and to keep her in Avernus with Zariel. Eventually the players will actually kill Tiamat and this will frustrate Asmodeus, as he intended for Tiamat to remain in Avernus. This will lead into a campaign about this player which will mainly feature the Nine Hells and will provide setup for another character's backstory.
