In this silly swap au, Taako would take Ren’s place (since she took his).
After the events of Glamorsprings, Taako was disgraced and attempted to hide himself from the world. He settled in Refuge and when the bubble went up, he was more than relieved to finally be free of consequence. He started up a little bar, only serving drinks and, still incredibly traumatized by what happened, he vowed off magic.
To him, it’s only been months since Glamorsprings, when it’s actually been 6 years.
Ren adores Taako; he’s the sole reason that she finally left the Underdark to live her own life. She considers him her greatest inspiration. You can imagine her shock when she sees him running a bar in a bubbled city.
