You've revealed to us (through chronological info) that the gargoyles' twenty-year cycle is "attuned to the earth" rather than something which is mostly internal (as I had earlier assumed).

How did this affect Katana during her timedances? Her and Brooklyn's two children are twenty years apart in age, as if the cycle had been internal for her, affected only by the time which passed for her, rather than affected by the "earth's cycles" and the different times she would journey to.
Is that simply a coincidence? Did she just happen in her travels to journey to two mating seasons, with a period of twenty years inbetween as subjectively perceived by the timedancers?
