Getting brainworms of a slow burn Rolan and traveling adventurer!Tav following the events of Baldur's Gate 3.
Tav leaving the city and becomes the hero of the Sword Coast, helping those in need. Tav being a near mythical figure in Faerun that appears when you are most in need and vanishes right after.
The only constant in their life is going back to stock up on equipment and unloading magical items they find on their travels at Ramazith's Tower. Maybe they even get invited back up to Rolan's office to talk about the acquisition of more rare magical artifacts - totally not because of Rolan Lia and Cal want to fuss over their latest injuries and scars while chiding them for not being careful enough and playing too much of a hero.
Tav having Rolan on sending speed dial for uh. quicker item delivery. totally. Tav keeping a stockpile of Galdur's Speedy Courier on themselves to send items and later little mementos that remind them of Rolan back to the Tower. Rolan making a waygate for Tav directly into the living area of the Tower because ' you come over enough already what's the point of going through the shop'. Tav moving in during the times they are back in Baldur's Gate for supplies since ' this tower is better fortified and we have so many spare rooms, you are just wasting gold on the inns unnecessarily. Rolan creating rings of protection for Tav because 'its ridiculous that you have to rely on so much armor to be safe, what happens if you like take it off - take it off to sleep, I mean, to sleep' (Lia snickering that he is some lovesick fool making rings for Tav already before they've even held hands)
Tav's renown as a folk hero growing in parallel with Rolan's fame as the archwizard of Baldur's Gate, but they are both where each other's stories began. Becoming legends to everyone else but still seeing each other as they were in the Grove, in the Underdark, in the mornings when the sun is rising in the Tower and it's just the two of them. They are each other's first supporters, and they are the ones to keep each other from being overwhelmed by the weight of their reputations.
Tav anchoring Rolan to being a mortal and those in need even when he begins doing ninth-level spells. Rolan being Tav's point of security and consistency, no matter how dangerous their journey or how far their road. Both of them traveling to the edge of the realm or the possibility of the Weave but always coming home to each other. And they haven't even kissed.
Just....Rolan and adventurer!Tav.
