Drannai Silverborn was a pyromaniac mage who created a solitaire set made of solidified elemental fire, which is regarded as very valuable. She had an accident while making the solitaire set and her lab exploded, killing her and scattering her flame fragments across Gielinor. The object of the Lost Her Marbles caper is to recover those flame fragments by pickpocketing various people so that Guildmaster Darren Lightfinger can sell them to a collector.
