fluent-nhibernate

I have this table structure and would like to map it using Fluent Hibernate (subclass if possible). I cannot change the structure because the database has too many records and might cause major applications rework. It would be easier if the Id from Party table was a foreign key in person and organization table, but in the particular scenario the database has person and organization key as a foreign key in party table. Any help would be great.

Party table

Id PersonId OrganizationId

Person table

Id FName LName

Organization table

Id OrgName OrgDescription
