How much fleshing out of the Tr'rask species mentioned in Desperate Hours did you do in writing the book? They are obviously large enough to cause impact tremors with their footfalls and formidable enough to subdue Kelpians and force them underground for survival. Beyond that do you coceptualize them as mamillian, reptialian, or something else? Do you have any ideas how the bred and cultivated the Kelpians as prey or for food? Thanks in advance.
