Nimrodel

1. This challenge begins with the selection of your matriarch. To pick one, she must fulfill two requirements. The first, obviously, is that she has to be biologically female. The second is that she must have never been bred before now. That's it; anything else goes! She can be from your clan already, from the Auction House, have any breed / color / gene combination, be immediately RTB or not -- the sky is the limit. The one thing I recommend without a doubt is that she'd be a dragon you'd permanently keep, because you're going to have her in your hands for quite some time.

If you find that you're tiring of your matriarch's look, feel free to scatterscroll her, breed change her, or alter her genes as much as you'd like. The only thing you cannot do is replace her with any other dragoness after the challenge begins.

2. Select the first mate for your matriarch. You may retrieve him over the Auction House, borrow a stud, or pick a permanent resident of your clan -- literally the only requirement for him is that he's biologically male and thus can produce offspring with her.

Note how this step says "first" mate. This is because your matriarch cannot breed with the same dragon twice across the duration of this challenge.

3. Breed them once they're both RTB and you have sufficient space! Make a note of how many children they've had and keep it. Maintaining count is key. I'd also recommend making a note of who the mate was, so that you never accidentally "double-dip."

4. Repeat the process from finding a new mate to sending the hatchlings off to find long-term homes until all 100+ hatchlings have found a place they belong!
