I assume that ALL the characters - Custom and Origin - have been reset by the tadpoles.
This is the only explanation that can even begin to explain the companions and I find it really off-putting.
The tadpoles have no reason to do this. Exactly the opposite. Why would they want weakened thralls? Getting an archmage would be a jackpot for the Absolute. Going through such lengths just to get level 1 cannon fodder doesn't make any sense. Minthara, Ragzlin and Nere aren't weakened. How convenient.
I think it's just a complete disconnect between writing and game mechanics. Everyone is legendary and amazing at level 1. Even though they get owned by goblins. Levels do not reflect actual power. By this logic an archdruid can also be a low level companion and you can slay Adamantine Golems at level 4.
And everyone gets to have an epic backstory except... you.
