Serious question:
Where did you find any connection between Mage Tower and Tadpole, or Illithids? O_o
It's a good question.
The best answer I have for you is that this is the way stories tend to work. There's connective tissue built throughout. Within mysteries, one searches for clues here and there, looking feverishly for what will one day feel obvious in hindsight.
Sure, these things could be completely unrelated. But I don't think it's a big leap to say that groundbreaking research into an anti-magical flower might have some connection to a stasis field that's impacting the main characters in a story, especially when all of these events are so provincially linked.
