What is the role of imperative form in this sentence?


> 「ケガはないかい?」ハリーを引っ張り上げて **立たせ** ながらケンタウルスが声をかけた。

Please help me understand why they used imperative form (立たせ) in this
sentence. I thought it is only used to give out order, request... and rarely
used in writing language ?




This 立たせ isn't imperative form but causative. 立たせろ is imperative form of
causative. 立たせる is causative and it means "to make someone stand".
