The Lan Shen Investigations Firm, also known as the LSI, are a group of private investigators under their leader Aiyana. Aiyana formed this group out of her desire to stop crime in a legal-ish and efficient manner. Aiyana will not tolerate any corruption within her group or take on any dirty jobs. They solve many cases that Yu Dao's police force are unable to solve along with cases civilians were offer them.
On hiatus until Book 1 concludes.
Characters who seek to join LSI should be Yu Dao residents since the group is located there. Members may not use illegal weaponry or forbidden bending arts with the exception of soundbending or bloodbending (in extreme circumstances). Due to the nature of their work, they wouldn't need to engage in combat as much as other factions. But should still be able to defend themselves against hostile suspects or enemies they'll possibly make. The group would try to obey the law, but certain exceptions may need to be made for the greater good. So like Faceless, only Chaotic Good and Neutral Good characters would be acceptable for membership
