Beloved Katya,
For your mission to this 'Fireball Palace', I have for you a gift. While my immediate aid might not align with the schedule, I have crafted for you twelve 'Runes of the Eclipse'. These runes each possess the capacity to conjure a small sphere of magical darkness numerous times before sundering to ash. My hope is that they might shield you from enemy archers or mages if their use is spent wisely.
Seek me to collect such, if you have wish of them.
Yours,
Acolyte Endora
