No thunder stolen. :)

20 years have passed since the adventurers first got on the Dungeons & Dragons ride. The artifacts don't function on Earth, no magic from the Realms does. Well... almost none. Each of you can once a day cast a modified version of the spell
[ +- ] Dream of the Blue Veil.
7th-level conjuration
Casting Time: 10 minutes
Range: 20 feet
Components: V, S, M (a magic item or a willing creature from the destination world)
Duration: 6 hours
You and up to eight willing creatures within range fall unconscious for the spells’ duration and experience visions of another world on the Material Plane, such as Oerth, Toril, Krynn, or Eberron. If the spell reaches its full duration, the visions conclude with each of you encountering and pulling back a mysterious blue curtain. The spell then ends with you mentally and physically transported to the world that was in the visions.
To cast this spell, you must have a magic item that originated on the world you wish to reach, and you must be aware of the world’s existence, even if you don’t know the world’s name. Your destination in the other world is a safe location within 1 mile of where the magic item was created. Alternatively, you can cast the spell if one of the affected creatures was born on the other world, which causes your destination to be a safe location within 1 mile of where that creature was born.
The spell ends early on a creature if that creature takes any damage, and the creature isn’t transported. If you take any damage, the spell ends for you and all other creatures, with none of you being transported.
TLDR: You can each travel from Earth to Toril and back for an unlimited amount of time since the great forces of the universe have accepted you all as joint citizens of Earth and Toril. When you arrive on Toril (usually at Presto's tower), your artifacts appear in your hands/on your bodies along with your gear, and they disappear when you arrive on Earth, leaving you in whatever you were wearing when you left. You can't bring anything from either world to the other via this spell. You can't use this spell to access any other planes. As far as you know, it is the only spell that works on Earth but the fact that it
does work implies that other spells might also work even though you haven't found any yet that do.
Most of the party live on Earth and visit Toril as they choose or as their help is requested. Presto, however, lives on Toril and visits Earth as he chooses, usually being the one to signal the others that mischief is afoot. He can get to Earth using other powerful teleportation spells if he desires but the Dream of the Blue Veil is his only way back should any portals he opens close.
You've battled Venger less and less frequently over the decades.
The redemption you helped him achieve seems to have been short-lived as he returned within a few years to the dark ways which previously damned him. Since Venger's own backsliding and subsequent recorruption of his sister, Karina, you've also seen Dungeon Master less and less as the little man seems to be on a personal quest to find a way to save his children yet again.
Apart from that, you're all free to decide what's happened to you and how you've lived for the past 20 years.
