You feel more humble as you feed the less fortunate.

Sister Abigail, the abbess of nuns shouts, 'Behold mortals, Sister Xortoth has
been promoted to elder nun'.

Sister Xortoth has been promoted to elder.

Abbess Abigail tells you, 'CONGRATULATION! sister. Your efforts have not been
vain and the long and hard journey you have done to get this position has
ended. The sisterhood now recognizes you as an elder nun and as a token I hand
you this fat ruler. It was used in the dawn of nuns by Sisters of Kofgaad a
long long time ago. Carry it with pride.'
Congratulations! You have just completed Path to sainthood!
You give a gamey pheasant to Gargoyle.
Took roughly ~2.5 months in a fresh nun reinc to get elders! Final task was a
bit intimidating, but with many hours and much nags I managed to get it done!
Would like to give a big thanks to everyone who helped out and put up with my
bullshit throughout the task(multiple tells asking to let me feed them etc
:D). One of my biggest accomplishments to date in this game.
