Pirate captain discovered text revealing climactic events (7)

'climactic events' is the definition.
The answer and definition can be both acts as well as being plural nouns.
Perhaps they are linked in a way I don't understand?

'pirate captain discovered text' is the wordplay.
'pirate' becomes 'org' (I can't justify this - if you can you should give a lot more credence to this answer).
'captain' becomes 'cap' (abbreviation).
'discovered' says to take the centre (dis-covered - outer letters removed).
'text' becomes 'SMS' (abbreviation for Short Message Service).
The centre of 'cap' is 'a'.
'org'+'a'+'sms'='ORGASMS'

'revealing' is the link.

Can you help me to learn more?
