Krosus defeated (1)
<Your direbeak hatchling squawks loudly and panics when very large creatures are nearby, even if they are friendly. It must learn to remain calm under pressure, even when facing creatures many times its size. Showing it an epic example of teamwork against a monster the size of a mountain might help.>
