MOD description
With this mod, Windhelm Sadri's Used Wares
Invitation to Elenwen's Reception (Counterfeit) is on sale.
All we are dealing with are legitimate items!

If you read that Invitation, unless you have started Diplomatic Immunity
The Diplomatic Immunity will start and warp to the Thalmor Embassy.
The flow from there is as per the main quest scenario, but as a change
Items will no longer be confiscated, Embassy gates and barracks will be unlocked and you can go out freely
You can hold a weapon, etc. You can also use fast travel and wait.
Next, Aristocrats will participate, which was supposed to be in Embassy
It's okay to proceed with the main quest from here, but my original purpose
I made it on the assumption that I would enjoy the party with the aristocrats.
Whenever you get tired of the party, you can go home.
You can also go inside Embassy and enjoy the party!

problem
I haven't tested it from here yet
Nobles participating in the Embassy will not be able to complete the Diplomatic Immunity
You may stay at the party forever.
General Tullius and Balgruuf the Greater, who have difficult conditions to join the party next
They speak the lines of the party even in the castle.
If you do, you may not be able to proceed with the main quest in the regular way at the end.
There may be various problems and bugs. Please enter only those who are prepared.
