Within no time, go-team draws the conclusion (5)

I believe the answer is:

omega

I'm a little stuck... Click here to teach me more about this clue!

'conclusion' is the definition.
(omega is a kind of conclusion)

I don't understand how the remainder of the clue works.

Can you help me to learn more?

(Other definitions for omega that I've seen before include "character in Greek literature?" , "Conclusion" , "completes a series" , "Final Greek letter" , ""The Alpha and the ___"" .)

I've seen this clue in The Hindu.
