The FYS Tileset is a pretty great tileset, personally my favorite enhanced classic tileset... But it did lack freeform dungeon tiles which limited the user to making typical square rooms. A while back I attempted to work on walls that fit stylistically using (I believe) Alestance's edited BS walls as a base, so huge credit to him! Anyways, today I decided to finish them off for someone. Enjoy!
