Basically, being originally an anthro version of a Legendary/Mythical, without knowing. It can have world shifting or not, side effects, can go mature (Although I have limits, and in notes), although I have no plot idea, so I'd like if you could make one.
How about... Stuff related to dragons again, basically linked to a product again, though not for the same goal.
The product would be to 'hide as a human being', though it takes time for it to work, and will cease to have effect if the daily chain's broken.
Basically, we would be related in any way, though one evening, let's just say I forgot to use said product...
Also, yes, you can end up TFing afterward.
