Have truly enjoyed the Reality Detour.
The Real World adventures are honestly one of the very best fanfiction works of art I have seen, and to me is the true hilight of this fiction.
May I suggest that if your creativity is running into difficulties, that you simplify the story somewhat. eg eliminate Draco and old evil mage, Squash DD and his cronies, fade the vampire clans, and remove lots of gold from the goblins when H/Hr retreat after being attacked by them.
The storms could be the disturbances from portals to the past being opened (by LV), or the time period coming to a close. I assure you that you still have plenty ongoing for your main theme - H/Hr and family with the new and different magics. Even return to the Real World with their family after LV is defeated. If ideas are still troubling, do a quick eliminate of LV, and write of a return to RW and setting up IDs and careers. This has to add to the 'Not Been Done Before'.
To conclude, it has not been my intention to criticize, so my apologies.
I repeat that the Reality Detour where our heroes matured is the best.
Cheers.
