My current king is becoming older - nearing 15 years, and I’ve begun my search for an heir. The problem is that I have no shortage of options, and I am indecisive. This is also the first time I’ll have properly gotten a new king (retired my first one early) so I’m kind of sad and apprehensive. Anyways, I’d like opinions on some of my options!

The option I’m generally leaning towards is Quibble. He’s a svelte pie with the Elysian base, and is clean. The only reason I might not choose him is because elysian isn’t a factor in combo bases, and he’s not related to my current king.

The second option would be my kings son who is a smilus and also clean. He doesn’t have a good base rn but I have base apps, none that are combo factors afaik though. He’s good because he’s my king’s son and a primal, which has kind of been my thing in the past.

Third option is a mudstone base, who again isn’t Jeremy’s son, and doesn’t have a combo factor base, although mudstone seems fairly rare. He is clean. I also have a MOD, so I’d give him that.

Fourth and final option is my kings daughter, Aya. What makes me lean towards her a little more than the second and third is that she inherited the ankh base, which both my kings have had, and it’s kind of part of pride lore. She is dirty though.

Help would be appreciated! Thank you!
