The cosmere awaits you! Hoid shows up in Mistborn, but only for a moment. And as much as he's written for the Stormlight Archives, there's actually only 3 books out right now. I guess Warbreaker kinda ties in, but it is technically its own series.

I am finding that it is extremely easy to get fancy eggs and fancy pets with fancy traits, so I think I am going to try to restrain myself and not buy anymore pets and try to breed some of my own. Thank you! But it is too easy to suddenly find myself with a full stable and hatchery, so I am going to try and figure out what to do with the pets I already have.

The fourth in my mind is Edgedancer, but I guess its more of a side novella. And thats really cool the Hoid is there, his conversations are some of my favorite to readespecially when he interacts with Kaladin.
And I totally understand the full stable and hatcheryits definetly a matter of restraint to keep from breeding and buying. Theyre all just so beautiful! XD

SO, that Reaper kelp, if you scroll down to where the traits are supposed to be, you see *Reaper Kelpari in blue right? Thats a PB. Themed have a yellow star and purple writing(themed are caught in the wild while PB are bred)
Now, Restrict Traits are like the Reaper Traits on that Kelp
When generating a pet, the Restrict traits have a * on them.
