As R and T's origins/information was asked about here is a bit of history of them.

Origins, straight from the dragons rumps.

Torri says "We are brother and sister, born like this from the same egg. Our mother and father were so proud, hydras are quite rare and respected in dragon society. We were sent to various high end schools and procured several degrees specializing in transformational magics and our own elemental specialties. We started out building our own small business a magic-adult-toy shop with funds from our parents and went our own way. The business is successful as we focus on premade items that were simple for laymen to use."

Rhylith says "Bah, bullshit and baloney the real story is simply that we're perverts and we were playing around in an abandoned adult magic shops as sprats. There were several interesting magic toys in there like a box-cutting magic trick that could actually separate body parts and so forth and allow someone to mold the parts like clay, or add things and then re connect them. Anyways after playing with various toys we ended up stuck together."

Torri says "Bah that's a slanderous lie you pervert.! No i'll tell you what really happened. One day while cheerfully walking though the city to head back to my high-rise condo, I was beset with these beast of a dragon who drugged me. I woke out strapped down to a table in a hospital smock. The slavering blue dragon above me flashing his wicked implements and occult spell books. His voice grating, "I live next to you but you don't even know i exist, i've asked you out a dozen times only to meet you cold-hearted rejection then you simply ignored me, not even acknowledging my existence! I'm going to make sure you can never ignore me again MWAHAHA.." He then pulled out a large needle, plunging into into my tender nubile flesh and injected me with something.. then I woke up screaming with him stuck to me!"
