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

'be somebody facing death' is the definition.
I can't judge whether this defines the answer.

'individual interrupting old king' is the wordplay.
'individual' becomes 'one' (an individual is one person).
'interrupting' indicates putting letters inside.
'old king' becomes 'GR' (Georgius Rex, Latin for King George).
'one' going into 'gr' is 'GONER'.

'will' is the link.

Can you help me to learn more?

(Other definitions for goner that I've seen before include "Nasty princess" , "One who can't be saved" , "person about to depart" , "I'm late" , "One past helping" .)
