Maybe there was some misunderstanding?
The situation last friday was that I did not know at which table I was going to play when I came to the location. We were still waiting for how many players were going to show up. I ended up getting a spot at @frogemiah’s table.
While I was thinking about which of my T2 characters I should play (and getting a new level 6 bard ready using one DM reward level-up), they recapped last session and the DM explained the setting. That was when I recognized the setting and thought it would be awesome if I could get my T3 character Ophelia back down to T2 and play her instead due to how well she would fit into the game.
Therefore I asked the DM about that - and the DM said yes.
Due to the lack of time (we all sat around the table and were ready to start), creating a new character wasn’t really an option, not even for me - the only options were either to play a character with no specific connection to the setting (either the new bard or one of my level 10 chars), or to play Ophelia, who actually has a very strong connection to the setting and storyline, but requires downleveling.
