You heroically defended the Church of All Souls in the Border Kingdom town of Emrys against an attack from foul undead creatures. The clergy of all the different faiths that worship there are greatly indebted to you.
Whenever you are adventuring in or around the town of Emrys, you may visit the Church of All Souls, and, regardless of your faith, request one spell a day from the Spellcasting Services table for free (as if you had the Acolyte Background). The only cost paid for the spell is the base price for the consumed material component, if any is required.

Inkpot and the scribes of Candlekeep are extremely grateful for your stories and account of your time in Warlock’s Crypt. In return, they have offered to teach you ancient Netherese as an immersion course; if you would like to learn ancient Netherese, you must spend 120 downtime days at Candlekeep doing nothing other than working on your knowledge of this language. If you are not interested in learning ancient Netherese, you may instead choose three spell scrolls of up to 5th level (tier 3) or 7th level (tier 4) for free from an approved Adventurers League resource.
