Obviously you're not going to outright die or turn into a mindflayer.
Are you quite sure? It wouldn't surprise me in the slightest that if you've begged, borrowed and stolen, exhausted all options, You turn into a mindflayer. That's the plot.
Ceremorphosis wouldn't actually work with multiple tadpoles in one host...most likely scenario is it would fail and in the process the host and tadpoles would die. If we go with the interpretation that we only use other tadpoles so ours can siphon power off them without actual insertion then we probably would be more susceptible to the tadpole's influence but it was inserted in stasis...clearly not intended to complete ceremorphosis until a signal is sent by whoever controls the stasis. The plan very much appears to be for a mass transformation at an intended time. Personally I wonder if by being allowed all this extra time and our tadpole having a lot more time in the host along with the opportunity to siphon power off other tadpoles might create a unique enough cisrcumstance that our character might transform not just into another mind flayer or into an ulitharid, but into the Adversary.
