Stark likes the kids and so do his caelbeasts, so others often seek him out as a babysitter.
Plus bonus of having the chance to take care of his best friend's kid!
Art by Me.
Stark (big guy), caelbeasts (4 of them perching) & kids (in his lap) belong to Me.
Asterlites, Caelbeasts, & Facelesses belong to Me.
