I am playing a newly Level3-Bard with the College of Lore. In her backstory she encountered the criminal group The Nine Swords in Westgate, who are protected from high up and her goal is to bring them to justice.
The PHB describes the College of Lore as
The college’s members gather in libraries and sometimes in actual colleges, complete with classrooms and dormitories, to share their lore with one another. They also meet at festivals or affairs of state, where they can expose corruption, unravel lies, and poke fun at self- important figures of authority.
We will start our next session in Baldur's Gate, and with respect to How to explain Bard getting College education suddenly?, I am wondering where she might find these other bards of her college.
Wandering around the docks and library, asking if someone saw another person singing very motivationally or knows of The Nine Swords seems a bit random and helpless. A mentor who taught her the first spells would certainly also tell her about where to find others or contact them, I think.
